Exam A

QUESTION 1Which statement is true about the use of data controls in JSF? (Choose the best answer.)

A. Only Oracle ADF Business Components can be exposed as data controls.B. Dragging a data control onto a JSF page generates a Java class that acts as a managed bean.C. An XXXpagedef.xml file holds detailed information about a JSF page’s use of data and operations exposed through ADF Data Controls.

D. Data controls eliminate the need to use expression language in your JSF code for binding the UI to data.E. A Databindings.cpx file holds names of managed beans that you map to UI elements.

Correct Answer: DSection: (none)Explanation

Explanation/Reference:Incorrect Answers:E: The DataBindings.cpx file maps individual pages to page definition files and declares which data controls defined in the DataControls.dcx file are being used bythe application.

QUESTION 2Which statement is false? (Choose the best answer.)

https://www.gratisexam.com/

A. A panelDashboard has the same rowHeight for all the rows.

B. AFStretchWidth in the style class of a panelGroupLayout causes it to fill the page horizontally.

C. panelGroupLayout cannot have a vertical scroll bar.

D. panelBox stretches if placed inside a panelStretchLayout center facet.

Correct Answer: CSection: (none)Explanation

https://www.gratisexam.com/

Explanation/Reference:Incorrect Answers:A: RowHeight is the height of the rows of the grid layout as a CSS length. panelDashboard stretches the panelBox children to fit within the width of a column and thespecified row height.B: ADF has a default styleClass called "AFStretchWidth" which could auto adjust the table width to let it occupy the whole horizontal space.

QUESTION 3Consider a bounded task flow input parameter called employeeId of type oracle.jbo.domain.Number . When defining the parameter in the bounded taskflow, if you do not define a value (destination) for the parameter, where does it get written to? (Choose the best answer.)

A. #{employeeId}

B. #{employee.employeeId}

C. #{pageFlowScope.employeeId}

D. #{pageFlowScope.employee.employeeId}

E. #{backingBeanScope.employeeId}

F. #{backingBeanScope.employee.employeeId}

Correct Answer: CSection: (none)Explanation

Explanation/Reference:For example, the page might specify #{pageFlowScope.empno} as a page parameter and a bounded task flow might specify #{pageFlowScope.employeeID} as thevalue of an input parameter definition.

The from-value on the view activity input page parameter would be #{pageFlowScope.employeeID} and the to-value would be #{pageFlowScope.empno}. Thisenables reuse of both the page definition and bounded task flow because you don't have to redefine parameters for every context in which each is used.

References: https://docs.oracle.com/cd/E23943_01/web.1111/b31974/taskflows_parameters.htm#ADFFD19858

QUESTION 4Which two scopes can you use to make a value in a managed bean available for at least three pages in a task flow? (Choose two.)

A. requestB. pageflowC. view

https://www.gratisexam.com/

D. applicationE. server

Correct Answer: BDSection: (none)Explanation

Explanation/Reference:B: Choose the pageflow scope if you want the managed bean to be accessible across the activities within a task flow. A managed bean that has a pageFlow scopeshares state with pages from the task flow that access it. A managed bean that has a pageFlow scope exists for the life span of the task flow.If another task flow'spage references the managed bean, the managed bean creates a separate instance of this object and adds it to the pageFlow scope of its task flow.

D: The application scope lasts until the application stops. Values that you store in a managed bean with this scope are available to every session and every requestthat uses the application.Avoid using this scope in a task flow because it persists beyond the life span of the task flow.

Incorrect Answers:A: Use request scope when the managed bean does not need to persist longer than the current request.

C: Use this scope for managed bean objects that are needed only within the current view activity and not across view activities. It defines scope for each view portthat ADF Controller manages, for example, a root browser window or an ADF region.The life span of this scope begins and ends when the current viewId of a view port changes. If you specify view, the application retains managed bean objects usedon a page as long as the user continues to interact with the page. These objects are automatically released when the user leaves the page.

E: There is no server scope

References: http://docs.oracle.com/cd/E15586_01/web.1111/b31974/taskflows.htm#CHDFAIGC

QUESTION 5Which three statements are true about declarative features of view objects? (Choose three.)

A. You can use view object bind variables to parameterize a view object where clause with values supplied at run time.

B. By default, a view object instance retrieves all database rows into the view object cache.C. To implement master-detail behavior between two view object instances, you define an association between those instances.D. A view accessor defines a validation expression that you apply to a view object attribute.E. A view object can include attributes whose values are based on SQL expressions rather than mapping directly to a database column.F. A view object definition can include many view criteria but you can choose which view criteria to apply for each view object instance.

Correct Answer: ACESection: (none)

https://www.gratisexam.com/

Explanation

Explanation/Reference:A: Declarative view objects, those are view objects that don't actually specify a hard coded query. Instead ADF creates their query at runtime, and it does it basedon the data that is requested in your UI layer. This can be a huge saver of both DB resources and network resources.

C: Just as with normal mode view objects, you can link view objects that you create in declarative SQL mode to other view objects to form master-detail hierarchiesof any complexity.

E: At runtime, when ADF Business Components works with JDBC to pass a query to the database and retrieve the result, the mechanism to retrieve the data is theSQL query. As an alternative to creating view objects that specify a SQL statement at design time, you can create entity-based view objects that contain no SQLstatements. This capability of the ADF Business Components design time and runtime is known as declarative SQL mode. When the data model developer workswith the wizard or editor for a view object in declarative SQL mode, they require no knowledge of SQL. In declarative SQL mode, the view object's metadata causesthe ADF Business Components runtime to generate the SQL query statements

QUESTION 6Which three statements are true about the default value for an entity object attribute? (Choose three.)

A. It can be a literal value.B. It can be defined by a Groovy expression.C. It can be defined by a SQL select statement.

D. It can be defined by an Expression Language (EL) statement.E. It can be defined by referencing a database stored procedure.

Correct Answer: ABDSection: (none)Explanation

Explanation/Reference:A: The Value field (in the Edit Attribute dialog) allows you to specify a static default value for the attribute when the Value Type is set to Literal. For example, you canset the default value of the ServiceRequest entity object's Status attribute to Open, or set the default value of the User entity object's UserRole attribute to user.

B: You can use a Groovy expression to define a default value for an attribute. This approach is useful if you want to be able to change default values at runtime.

D: Groovy scripting logic is similar to Expression Language (EL)

QUESTION 7A backing bean for a page must hold its value over multiple requests for the current user. Which three bean scopes are applicable? (Choose three.)

A. requestScopeB. backingBeanScopeC. viewScopeD. pageFlowScopeE. sessionScopeF. applicationScope

Correct Answer: CDESection: (none)Explanation

Explanation/Reference:C: View scope: The object is available until the view ID for the current view activity changes. This becomes handy when you use partial page rendering. If you havea dependent list box, you might send a server request to refresh the list box. When a response is returned, the request scope will be gone but the view scope will bestill there.

D: A pageFlow scope exists for each task flow instance and has a lifespan between request and session scope. The lifetime of the scope spans across all pages ina bounded task flow.

E: Session scope: The object is available for the duration of the session, which is user instance-specific. A use case for a session scope bean is a user info beanthat stores information about a user, which is read from the database or an LDAP server, to avoid unnecessary queries.

Incorrect Answers:A: Request scope: The object is available from the time an HTTP request is made until a response is sent back to the client. From another perspective, a requestscope starts with a request to be issued from one view to another for navigation cases that don't perform a redirect but a default server-side forward. The scopespans across all non-view activities that follow the view of interest to the next view activity.

B: The backing bean scope is comparable to the request scope, with the difference in that it exists for a specific client component. In general, all managed beansused in reusable components should be configured to backingBean scope. For example, bounded task flows that are designed to be regions on a page should usethe backingBean scope if more than one instance of the task flow is expected to be on a single page.

F: Application scope: An application scope object is available for the duration of the application and is shared among users. This scope may be used to hold staticobjects that are the same for all users.

QUESTION 8Identify three statements that are true about JSF. (Choose three.)

https://www.gratisexam.com/

A. Components are used to define page structure.B. Navigation between pages is defined outside of the JSF page in the metadata.C. Managed beans can have only one of two memory scopes.D. Managed beans can be accessed from more than one page.E. JSF does not support template creation for pages.

Correct Answer: ABDSection: (none)Explanation

Explanation/Reference:Incorrect:Not C: Managed beans can have the following scopes: Application, session, PageFlow, view, request, BackingBean.

Not E: JavaServer Faces (JSF) technology provides the tools to implement user interfaces that are easy to extend and reuse. Templating is a useful Faceletsfeature that allows you to create a page that will act as the base, or template, for the other pages in an application. By using templates, you can reuse code andavoid recreating similarly constructed pages. Templating also helps in maintaining a standard look and feel in an application with a large number of pages.

References: http://docs.oracle.com/javaee/6/tutorial/doc/giqxp.html

QUESTION 9Your page contains the following code that is invoked on an action by the current user:

<af:setPropertyListener from="#{applicant:surname}" to="#(...)" type="action"/>

To receive the value from the to property of the af:setPropertyListener, you create a managed bean as follows:

package view;

public class Employee { String lastName;

public void setLastName(String lastName) { this .lastName = lastName; } public String getLastName() { return lastName;}

In the adfc- сonfig.xml file, the managed bean is configured as:>

<managed-bean>

https://www.gratisexam.com/

<managed-bean-name>emp</managed-bean-name> <managed-bean-class>view. Employee</managed-bea n-class> <managed bean-scope>pageFlowScope</managed-bean -scope></managed-bean>

What EL expression would you write in the af:setPropertyListener "to" property to write the value to the lastName string of the Employee class?(Choose the best answer.)

A. to=”#{lastName}”

B. to=”#{LastName}”

C. to=”#{pageFlowScope.emp.lastName)”

D. to=”#{pageFlowScope.Emp.lastName}”

E. to=”#{emp.lastName}”

F. to=”#{pageFlowScope.emp.LastName}”

Correct Answer: CSection: (none)Explanation

Explanation/Reference:For example, the page might specify #{pageFlowScope.empno} as a page parameter and a bounded task flow might specify #{pageFlowScope.employeeID} as thevalue of an input parameter definition.

The from-value on the view activity input page parameter would be #{pageFlowScope.employeeID} and the to-value would be #{pageFlowScope.empno}. Thisenables reuse of both the page definition and bounded task flow because you don't have to redefine parameters for every context in which each is used.

QUESTION 10Which three steps would you perform to enable security for an ADF application? (Choose three.)

https://www.gratisexam.com/

A. Define authentication and authorization by using the configure ADF Security wizard.B. Define which HTML pages must be secured.

https://www.gratisexam.com/

C. Grant roles access rights to bounded task flows.D. Grant roles access rights to unbounded task flows.E. Deploy the application to a Java EE Security-enabled server to test the user roles.F. Grant roles access rights to pagedefs for views in unbounded task flows.

Correct Answer: ABCSection: (none)Explanation

Explanation/Reference:A: The Configure ADF Security wizard allows you to choose to enable authentication and authorization separately.

C: ADF bounded task flow protects the entry point to the task flow, which in turn controls the user's access to the pages contained by the flow.

B: To grant public access to ADF security-aware resources:1. From the Application menu, choose Secure > Resource Grants.2. In the Resource Grants page of the jazn-data.xml file overview editor, select one of the following resources from the Resource Types dropdown list:

Task Flow when you want to make a bounded task flow public. The application displays the web pages under the permission you define for the task flow itself.Thus, all constituent web pages of the bounded task flow will become public.Web Page when you want to make individual web pages public. Typically, these pages are defined by an unbounded task flow and are top-level pages in theapplication, such as a home page.

Incorrect Answers:D, F: The unbounded task flow is not an ADF security-aware component and allows no grants.

QUESTION 11For what purpose would you use the entity object attribute setting Change Indicator? (Choose the best answer.)

A. to highlight the attribute in the UI with a border when the original attribute value has been changedB. to fire an entity object custom method as soon as the original attribute value has been changedC. to automatically lock the corresponding record in the databaseD. to automatically refresh the attribute value if the underlying data in the database is changed by another userE. to define an attribute that the framework uses to check whether the update is about to happen on underlying stale data in the database

Correct Answer: CSection: (none)Explanation

https://www.gratisexam.com/

Explanation/Reference:By default, during commit operation, ADF scans each changed attribute from the current row and compares value in the DB. If it locates changed values in DB,reports error about another user changes in the same row. While this is expected functionality, there are use case when we want to allow commit, even data waschanged already by someone else. For example, in more complex systems, data is updated by PL/SQL procedures, we don't want to inform user with error aboutthis. There is a way to override lock method in EO implementation class, catch lock error and raise lock again. This works, but there is different way - to use ChangeIndicator. This property defines specific attribute to be responsible for row data changes tracking, instead of checking every attribute. Only if Change Indicatorattribute value will be changed in DB, then current row changes will be prevented and user will be informed about someone else changes in the same row.

QUESTION 12Which three statements are true about af:panelTabbed ? (Choose three.)

A. Tab position can be only top or bottom.B. Content inside a tab can stretch horizontally.C. You can use icons instead of text on tabs.D. You can have only one disclosed tab at a time.E. You cannot have an af:panelTabbed component inside one of the tabs.

Correct Answer: BDESection: (none)Explanation

Explanation/Reference:E: The panelTabbed control can be used to display a group of contents that belongs to a showDetailItem.

Incorrect Answers:A: Valid positions of the tab bar are: bove, both, below, start, end, left, right

Which option represents the source file(s) that are typically created for you? (Choose the best answer.)

A. EmployeesView.xml

B. EmployeesViewImpl.java

C. EmployeesViewRowImpl.java

D. EmployeesView.sql

https://www.gratisexam.com/

E. EmployeesView.xml and EmployeesViewImpl.java

Correct Answer: ASection: (none)Explanation

Explanation/Reference:What Happens When You Create an Entity-Based View Object

When you create an entity-based view object, JDeveloper creates the XML component definition file that represents the view object's declarative settings and savesit in the directory that corresponds to the name of its package. For example, if the view object was named StaffList in the devguide.model.queries package, so theXML file created will be ./devguide/model/queries/StaffList.xml under the project's source path. This XML file contains the information about the SQL query, thename of the entity usage, and the properties of each attribute. If you're curious to see its contents, you can see the XML file for the view object by selecting the viewobject in the Application Navigator and looking in the corresponding Sources folder in the Structure Window. Double-clicking on the StaffList.xml node will open theXML in an editor so you can inspect it.

QUESTION 14Which two statements describe the characteristics of an entity object? (Choose two.)

A. An entity object represents a cache for records retrieved from the database.B. An entity object includes an ORDER clause to allow you to order the data in it.

C. An entity object includes a WHERE clause to allow you to shape the data in it.

D. Every column in a database table must be represented as an entity object attribute.E. An entity object definition is described in XML.

Correct Answer: ADSection: (none)Explanation

Explanation/Reference:A: An entity object caches data from a database and provides an object-oriented representation of it.D: When you use a Business Components for Java wizard to create entity objects from existing tables, each database table becomes an entity object. Each columnin the database table becomes an entity object attribute, which can have the same name as the column or a different name that is more meaningful to yourbusiness application.

QUESTION 17Consider a case where a view does not load with the expected data. Where would you set a breakpoint to debug the issue? (Choose the best answer.)

A. the executable binding for the iterator on the pagedef for the viewB. a router activity that is used to determine where to send the user after selecting a row in the viewC. the partialTriggers property of the data bound component in the view

D. the value binding for the iterator on the pagedef for the view

Correct Answer: DSection: (none)Explanation

Explanation/Reference:You use the ADF Declarative Debugger features in JDeveloper to declaratively set breakpoints on ADF task flow activities, page definition executables, method,action, and value bindings, and ADF Lifecycle phases.

The Declarative Breakpoint Before/After attribute value binding pauses debugging before or after the attribute's setInputValue() ADF source code method isexecuted. New values will be the parameters to setInputValue().

QUESTION 24Which two statements describe the characteristics of an application module? (Choose two.)

A. It provides the database transaction for the queries that it encapsulates.B. It defines view object instances to implement an application use case.C. It defines entity object instances to implement an application use case.D. There is a one-to-one mapping between view objects and application modules.E. Each ADF application has only one application module.

Correct Answer: ABSection: (none)Explanation

Explanation/Reference:A: In general, one application module instance owns a single database transaction. All changes made through that instance are made in a single transaction, whichcan be rolled back or committed at any time.

B: Oracle ADF application modules are business components that represent particular application tasks. The application module provides a data model for the taskby aggregating the view object and view link instances required for the task. It also provides services that help the client accomplish the task. For example, anapplication module can represent and assist with tasks such as:

Updating customer informationCreating a new orderProcessing salary increases

Incorrect Aanswers:D: An application module contains view object instances that retrieve the data needed by the client, as well as view link instances that specify the relationshipsbetween the view object instances. The view object and view link instances can be represented by a tree, called the application module's data model.

It is necessary to develop completely different applications for mobile browsers, desktop browsers, and other clients.E. ADF can be used to deploy server-based web applications as native mobile device applications.

Correct Answer: ACSection: (none)Explanation

Explanation/Reference:A: Oracle Application Development Framework Mobile (ADF Mobile) browser is a standards-based framework that enables the rapid development of browser-basedenterprise mobile applications. Its mobile-specific extensions to JSF enable you to develop mobile applications using the same methodologies for developing JSFapplications for the desktop.

QUESTION 30Select three benefits that ADF Data Controls provide. (Choose three.)

A. They abstract the UI developer from the technology used to implement business logic.B. They reduce the need to write managed beans.C. They automate Ajax updates to the UI.D. They enable drag-and-drop of data objects to UI component bindings.E. They directly connect your UI to the database tables.

Correct Answer: ABDSection: (none)Explanation

https://www.gratisexam.com/

Explanation/Reference:B: J2EE developers who do not want to rely on Oracle-specific libraries may use managed beans instead of the ADF data control. This is more complex.

AD: At a high level, the declarative development process for an application that contains data controls usually involves, among others, the following core steps:Creating data controls for your services: Once you have created your business services, you create the data controls that use metadata interfaces to abstractthe implementation of those services and describe their operations and data collections, including information about the properties, methods, and types involved.These data controls are displayed in the Data Controls panel and can be dragged to pages to create databound UI components.Adding declarative metadata to your data controls: You can augment your data controls with UI control hints, validation rules, criteria for use in search forms,and other features.Implementing the user interface: JDeveloper's Data Controls panel contains a representation of the services for your application. You can drag an object fromthe Data Controls panel onto a page and select the UI component you want to display the underlying data. For UI components that are not databound, you usethe Components window to drag and drop components. JDeveloper creates all the page code for you.

QUESTION 31When creating a bounded task flow that uses ADF Business Components, which two steps do you need to perform to enable the task flow to manage its owntransaction? (Choose two.)

A. Define transaction properties at the task-flow level.B. Include a phaseListener in a managed bean with methods for commit and rollback.

C. Add the application module commit and rollback operations as buttons or links on the last JSF page of the flow.D. Define task flow return activities in the flow and associate “End transaction” attribute values with them.

Correct Answer: ADSection: (none)Explanation

Explanation/Reference:A: To enable a bounded task flow to run as a transaction:1. In the overview editor for the called bounded task flow, click Behavior and expand the Transaction section.

2. Choose one of the following from the dropdown list:<No Controller Transaction>: The called bounded task flow does not participate in any transaction management.Always Use Existing Transaction: When called, the bounded task flow participates in an existing transaction already in progress.Use Existing Transaction If Possible: When called, the bounded task flow either participates in an existing transaction if one exists, or starts a new transactionupon entry of the bounded task flow if one doesn't exist.Always Begin New Transaction: A new transaction starts when the bounded task flow is entered, regardless of whether or not a transaction is in progress. Thenew transaction completes when the bounded task flow exits.

https://www.gratisexam.com/

D: 1. Select the task flow return activity in the called bounded task flow.2. In the Property Inspector, expand the Behavior section.If the called bounded task flow supports creation of a new transaction (bounded task flow specifies Use Existing Transaction If Possible or Always Begin NewTransaction options), select one of the following in the End Transaction dropdown list:

commit: Select to commit the existing transaction to the database.rollback: Select to roll back a new transaction to its initial state on task flow entry. This has the same effect as cancelling the transaction.

QUESTION 32Which statement is true about the role of bindings within the ADF Model layer of ADF? (Choose the best answer.)

A. The binding is a Java API for reading and writing data directly between ADF Business Components and ADF Faces.B. There is a one-to-one mapping such that each data control has only one binding.C. There are three types of bindings: method, attribute, and table.D. Expression Language is used to connect a UI component to a binding.E. Bindings can be created only by dragging and dropping from the Data Controls window.

Correct Answer: DSection: (none)Explanation

Explanation/Reference:You can view the binding in your application in any one of several ways. One way is in the source code view of a web page, where binding references appear inexpressions that get evaluated at runtime using the expression language (EL) features. In the code view, the expression looks like this:

<c:forEach var="rv" items="${bindings.DataBindingObject.theCollectionProperty}"

Incorrect Answers:C: Oracle ADF provides several types of binding objects to support the attributes and operations exposed by the Oracle ADF data controls for a particular businessobject:

Iterator binding, one per accessor attribute that your page or panel displays. Iterates over the business objects of the data collection and maintains the rowcurrency and state.Value bindings, one for each databound UI component. Provides access to data.Action binding, one for each button component. Provides access to operations defined by the business object.

E: You create bindings in JDeveloper through your interaction with the Data Control Palette, a visual editor, the Structure window, and the Property Inspector.

QUESTION 33You access a page in your ADF application that refers to bindings calling АDF Business Components.

Which statement is true at run time about the ADF Business Component application module? (Choose the best answer.)

A. An application module is automatically instantiated for each user session and allocated to that user for the life of their session.B. The programmer must instantiate an application module in a JSF managed bean and carry the application module for the life of the user session.C. One application module bean is instantiated and shared by all user sessions.D. An application module instance is checked out of the application module pool and given to the user session for at least that request, or longer depending on the

system load.

Correct Answer: ASection: (none)Explanation

Explanation/Reference:The application module is the "work unit" container that includes instances of the reusable view objects required for the use case in question, related throughmetadata to the underlying entity objects in your reusable business domain layer whose information the use case is presenting or modifying.

Your application module works with a Transaction object that acquires a database connection and coordinates saving or rolling back changes made to entityobjects.

The related Session object provides runtime information about the current application user.

QUESTION 34Which statement describes the Oracle implementation of model-view-controller (MVC)? (Choose the best answer.)

A. Oracle ADF provides a "pure" implementation of MVC, with the model layer handling page navigation and encapsulating business logic.B. ADF Controller provides support for application tasks such as validation, state management, security, and business-process orchestration.C. ADF bindings provide a layer of abstraction on top of the business services to enable the view and controller layers to work with different implementations of

business services.D. JSF Controller is the best choice for ADF Faces-based web applications because it enables you to break up an application's page flow into re-usable flows.

Correct Answer: CSection: (none)Explanation

https://www.gratisexam.com/

Explanation/Reference:The Role of Oracle ADF for J2EE ApplicationsJDeveloper includes an integrated J2EE runtime framework known as Oracle Application Development Framework (Oracle ADF) . Oracle ADF increases thecooperation between the MVC layers both in the design time and the runtime and, importantly, eases the incorporation of complex business services into theapplication model layer.

Specifically, ADF provides these benefits to J2EE application development:* Provides a thin model layer that adapts diverse business services, thus permitting views to be created in a similar fashion, independent of their data source/ Model layer - A thin model layer that adapts and combines a full range of business services as desired, including Oracle ADF Business Components, OracleTopLink mappings, JavaBeans, Enterprise JavaBeans, and web services.* Optionally, provides transaction control support to the model layer and permits web applications to scale better* Cooperates with the highly visual design tools in the JDeveloper IDE and enables an integrated view of the entire J2EE application project

QUESTION 35Your database has a strict security requirement that whenever users select from any table in the database schema, they must append the select statement withan additional where predicate that returns only records WHERE owner = :pUserName. This restricts users to seeing only records that they own.

When you design and develop the ADF Business Components in your ADF application, there will be more than 100 view objects that select against this database.You want to build a solution that not only ensures all your developers, when writing view objects, meet the database's strict security requirement, but takes the leastamount of development effort for your entire team and is easy to maintain in the long term.

Identify the correct solution. (Choose the best answer.)

A. Define a view criteria on each view object at design time to apply the predicate to the corresponding view object, ensuring the view criteria is defined against theview object instance in the Application Module Editor.

B. Override each view object's ViewObjectImpl class methods to programmatically modify each view object's where clause at run time to add the predicate tothe select clause regardless of the query executed.

C. Create a complete set of custom ADF Business Component framework classes for your business components and then override your custom ViewObjectImpl class to programmatically modify each view object’s where clause at run time to append the predicate.

D. In each view object, simply type the predicate into the WHERE clause of the View Object Editor query page.

QUESTION 39Which two components allow you to divide your page into two sections, where one section can be collapsed and expanded by the user, without the need to codelogic in a backing bean? (Choose two.)

A. af:panelBorderLayout

B. af:panelSplitter

C. af:stretchLayout

D. af:panelDrawer

E. af:panelTabbed

Correct Answer: ABSection: (none)Explanation

Explanation/Reference:A: The panelBorderLayout component is a layout element which lays out all of its children consecutively in its middle, and supports twelve other facets: top, bottom,left, right, start and end. Clients should use only one of left/right or start/end for each side, in any one container, but if both are used, left/right "wins". Left, InnerLeft/Right InnerRight always means left/right regardless of LTR or RTL. Start, InnerStart/End, InnerEnd will respect bidi setting.B: PanelSplitters are used to divide a region into two parts with a repositionable divider. The two parts are identified as the "first" facet and the "second" facet. If thecontained component supports it, the contents of a section will stretch to fill up all available space in that section. The panel splitter can be adjusted with the mouse,

https://www.gratisexam.com/

by pressing a collapse button, or by use of the arrow keys when the splitter is selected.

Incorrect Answres:C: The panelStretchLayout component stretches the child in the center facet to fill all of available space. The available space may be constrained by the presence ofother children in the top/bottom/start/end facets.

D: The panelDrawer control can be used to display a group of showDetailItems. Drawer "handles", aka tabs, represent the showDetailItem children. Selecting a tab/handle opens the drawer and displays the associated showDetailItem.

E: The panelTabbed control can be used to display a group of contents that belongs to a showDetailItem. Tab bar(s) with tabs representing the showDetailItemchildren are displayed. Selecting a tab, displays the associated showDetailItem.

Explanation/Reference:B: The setWhereClause method sets a WHERE clause bind value of the View Object's query statement.

E: The createViewCriteria method creates a new view criteria (that is, "Query by Example") object for this View Object. A view criteria object is an alternative tousing an arbitrary SQL statement. A view criteria is a list of row criteria for a View Object's WHERE clause, where a row criteria is an array containing criteria for theindividual attributes.A view criteria is a more structured way of creating a SQL query WHERE clause. After setting various conditions for the view criteria object, the application can callthe applyViewCriteria method, which applies the view criteria to this View Object.
