Common Use Cases

Visualforce ControllersApex for constructing dynamic pages

ViewstateHashed information block to track server side transports

Reducing Viewstate

//Transient data that does not get sent back, //reduces viewstatetransient String userName {get; set;}

//Static and/or private vars //also do not become part of the viewstatestatic private integer VERSION_NUMBER = 1;

Reducing Viewstate

//Asynchronous JavaScript callback. No viewstate.//RemoteAction is static, so has no access to Controller context@RemoteActionpublic static Account retrieveAccount(ID accountId) { try { Account a = [SELECT ID, Name from ACCOUNT WHERE Id =:accountID LIMIT 1]; return a; } catch (DMLException e) { return null; }}

Handling Parameters

//check the existence of the query parameterif(ApexPages.currentPage().getParameters().containsKey(‘id’)) { try {

Id aid = ApexPages.currentPage().getParameters().get(‘id’); Account a =

[SELECT Id, Name, BillingStreet FROM Account WHERE ID =: aid]; } catch(QueryException ex) { ApexPages.addMessage(new ApexPages.Message( ApexPages.Severity.FATAL, ex.getMessage())); return; } }

SOQL Injection

String account_name = ApexPages.currentPage().getParameters().get('name');

account_name = String.escapeSingleQuotes(account_name);

List<Account> accounts = Database.query('SELECT ID FROM Account WHERE Name

= '+account_name);

Cookies

//Cookie = //new Cookie(String name, String value, String path, // Integer milliseconds, Boolean isHTTPSOnly)public PageReference setCookies() {Cookie companyName =

new Cookie('accountName','TestCo',null,315569260,false); ApexPages.currentPage().setCookies(new Cookie[]

{companyName}); return null; } public String getCookieValue() { return ApexPages.currentPage().

getCookies().get('accountName').getValue(); }

Inheritance and Construction

public with sharing class PageController implements SiteController {

public PageController() { } public PageController(ApexPages.StandardController stc) { }

Controlling Redirect

//Stay on same pagereturn null;

//New page, no ViewstatePageReference newPage = new Page.NewPage();newPage.setRedirect(true);return newPage;

//New page, retain ViewstatePageReference newPage = new Page.NewPage();newPage.setRedirect(false);return newPage;

Unit Testing Pages

//Set test pageTest.setCurrentPage(Page.VisualforcePage);

//Set test dataAccount a = new Account(Name='TestCo');insert a;

//Set test paramsApexPages.currentPage().getParameters().put('id',a.Id);

//Instatiate ControllerSomeController controller = new SomeController();

//Make assertionSystem.assertEquals(controller.AccountId,a.Id)

“Universal Connectors”

Apex TriggersEvent based programmatic logic

Controlling Flow

trigger LineItemTrigger on Line_Item__c (before insert,

before update) { //separate before and after if(Trigger.isBefore) { //separate events if(Trigger.isInsert) {

System.debug(‘BEFORE INSERT’); DelegateClass.performLogic(Trigger.new); //

Delegates

public class BlacklistFilterDelegate{ public static Integer FEED_POST = 1; public static Integer FEED_COMMENT = 2; public static Integer USER_STATUS = 3; List<PatternHelper> patterns {set; get;} Map<Id, PatternHelper> matchedPosts {set; get;} public BlacklistFilterDelegate() { patterns = new List<PatternHelper>(); matchedPosts = new Map<Id, PatternHelper>(); preparePatterns(); }

Static Flags

public with sharing class AccUpdatesControl { // This class is used to set flag to prevent multiple calls public static boolean calledOnce = false; public static boolean ProdUpdateTrigger = false;

}

Chatter Triggers

trigger AddRegexTrigger on Blacklisted_Word__c (before insert, before update) {

for (Blacklisted_Word__c f : trigger.new) { if(f.Custom_Expression__c != NULL) { f.Word__c = ''; f.Match_Whole_Words_Only__c = false; f.RegexValue__c = f.Custom_Expression__c; } else f.RegexValue__c = RegexHelper.toRegex(f.Word__c, f.Match_Whole_Words_Only__c); } }

Scheduled ApexCron-like functionality to schedule Apex tasks

Schedulable Interface

global with sharing class WarehouseUtil implements Schedulable { //General constructor global WarehouseUtil() {} //Scheduled execute global void execute(SchedulableContext ctx) { //Use static method for checking dated invoices WarehouseUtil.checkForDatedInvoices(); }

Schedulable Interface

System.schedule('testSchedule','0 0 13 * * ?',new WarehouseUtil());Via Apex

Via Web UI

Batch ApexFunctionality for Apex to run continuously in the background

Batchable Interface

global with sharing class WarehouseUtil implements Database.Batchable<sObject> {

//Batch execute interface global Database.QueryLocator start(Database.BatchableContext BC){ //Start on next context } global void execute(Database.BatchableContext BC,

List<sObject> scope) { //Execute on current scope } global void finish(Database.BatchableContext BC) { //Finish and clean up context }

}

Unit Testing

Test.StartTest(); System.schedule('testSchedule','0 0 13 * * ?',new,WarehouseUtil()); ID batchprocessid = Database.executeBatch(new WarehouseUtil());Test.StopTest();

OAuthIndustry standard method of user authentication

RemoteApplication

SalesforcePlatform

Sends App Credentials

User logs in,Token sent to callback

Confirms token

Send access token

Maintain session withrefresh token

OAuth2 Flow

Apex EndpointsExposing Apex methods via SOAP and REST

Apex SOAP

global class MyWebService { webService static Id makeContact(String lastName, Account a) { Contact c = new Contact(lastName = 'Weissman',

AccountId = a.Id); insert c; return c.id; }}

Apex REST

@RestResource(urlMapping='/CaseManagement/v1/*')global with sharing class CaseMgmtService{

@HttpPost global static String attachPic(){ RestRequest req = RestContext.request; RestResponse res = Restcontext.response; Id caseId = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1); Blob picture = req.requestBody; Attachment a = new Attachment (ParentId = caseId, Body = picture, ContentType = 'image/

Apex EmailClasses to handle both incoming and outgoing email

Outgoing Email

Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage(); String body = count+' closed records older than 90 days have been deleted';

//Set addresses based on labelmail.setToAddresses(Label.emaillist.split(','));mail.setSubject ('[Warehouse] Dated Invoices'); mail.setPlainTextBody(body); //Send the emailMessaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});

Incoming Email

global class PageHitsController implements Messaging.InboundEmailHandler { global Messaging.InboundEmailResult handleInboundEmail( Messaging.inboundEmail email, Messaging.InboundEnvelope env) { if(email.textAttachments.size() > 0) { Messaging.InboundEmail.TextAttachment csvDoc =

email.textAttachments[0]; PageHitsController.uploadCSVData(csvDoc.body); } Messaging.InboundEmailResult result = new

Messaging.InboundEmailResult(); result.success = true; return result; }
