Apex 14. Introduction to Apex Object-Oriented Language Dot Notation Syntax Case Insenstive First Class Citizen on the Platform 15. Apex Anatomy Chapter 1: public with sharing class myControllerExtension implements Util { private final Account acct; public Contact newContact {get; set;} public myControllerExtension(ApexPages.StandardController stdController) { this.acct = (Account)stdController.getRecord(); } public PageReference associateNewContact(Id cid) { newContact = [SELECT Id, Account from Contact WHERE Id =: cid LIMIT 1]; newContact.Account = acct; update newContact; } } Class and Interface based Scoped Variables Inline SOQL Inline DML 16. Developer Console Browser Based IDE Create and Edit Classes Create and Edit Triggers Run Unit Tests Review Debug Logs 17. Apex Triggers Event Based Logic Associated with Object Types Before or After: Insert Update Delete Undelete 18. 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); 19. Static Flags public with sharing class AccUpdatesControl { // This class is used to prevent multiple calls public static boolean calledOnce = false; public static boolean ProdUpdateTrigger = false; } 20. 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; } } } 21. Trigger Tutorial Basic: Tutorial 2 Intermediate: Tutorial 4 Beyond Intermediate: http://bit.ly/ELEV-triggers http://bit.ly/elevate_adv_workbook 22. Unit Testing in Apex Built in support for testing Test Utility Class Annotation Test Method Annotation Test Data build up and tear down Unit test coverage is required Must have at least 75% of code covered Why is it required? 23. Unit Testing Declare Classes/Code as Test isTest Annotation testmethod keyword Default data scope is test only 24. Testing Context // this is where the context of your test begins Test.StartTest(); //execute future calls, batch apex, scheduled apex // this is where the context ends Text.StopTest(); System.assertEquals(a,b); //now begin assertions 25. Testing Permissions //Set up user User u1 = [SELECT Id FROM User WHERE Alias='auser']; //Run As U1 System.RunAs(u1){ //do stuff only u1 can do } 26. Static Resource Data List invoices = Test.loadData(Invoice__c.sObjectType, 'InvoiceData'); update invoices; 27. Mock HTTP Endpoints @isTest global class MockHttp implements HttpCalloutMock { global HTTPResponse respond(HTTPRequest req) { // Create a fake response HttpResponse res = new HttpResponse(); res.setHeader('Content-Type', 'application/json'); res.setBody('{"foo":"bar"}'); res.setStatusCode(200); return res; } } 28. Mock HTTP Endpoints @isTest private class CalloutClassTest { static void testCallout() { Test.setMock(HttpCalloutMock.class, new MockHttp()); HttpResponse res = CalloutClass.getInfoFromExternalService(); // Verify response received contains fake values String actualValue = res.getBody(); String expectedValue = '{"foo":"bar"}'; System.assertEquals(actualValue, expectedValue); } } 29. Unit Testing Tutorial 30. Batch Apex 31. Apex Batch Processing Governor Limits Various limitations around resource usage Asynchronous processing Send your job to a queue and we promise to run it Can be scheduled to run later Kind of like a chron job 32. Batchable Interface global with sharing class WHUtil implements Database.Batchable { global Database.QueryLocator start(Database.BatchableContext BC) { //Start on next context } global void execute(Database.BatchableContext BC, List scope) { //Execute on current scope } global void finish(Database.BatchableContext BC) { //Finish and clean up context } } 33. Implementing Apex Batch Processing Apex Batch Processing Tutorial 34. Scheduled Apex 35. 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(); } } 36. Schedulable Interface System.schedule('testSchedule','0 0 13 * * ?', new WarehouseUtil()); Via Apex Via Web UI 37. Unit Testing Batch Apex Test.StartTest(); System.schedule(once','0 0 13 * * ?',new,WarehouseUtil()); ID batchprocessid = Database.executeBatch(new WarehouseUtil()); Test.StopTest(); 38. Scheduling Apex Apex Scheduling Tutorial 39. Apex REST Services 40. 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/ 41. Apex REST Services REST Services with Apex Tutorial 42. Visualforce 43. Framework Server-side compiled web pages (Think PHP, JSP, etc.) Easily create salesforce UI Standard-compliant Can Interact With Apex for Custom Logic 44. Visualforce Tags 45. Hashed information block to track server side transports Viewstate 46. Apex Form Required for standard salesforce post Incurs Viewstate Overhead aspdoifuapknva894372h 4ofincao98vh0q938hfoq iwnbdco8q73h0o9fqubov ilbodfubqo3e8ufbw 47. Interacting with Apex ActionFunction allows direct binding of variables ActionFunction requires ViewState JavaScript Remoting binds to static methods JavaScript Remoting uses no ViewState Transient, Private and Static reduce Viewstate 48. Apex Remote Action Static No View State Invoked through JS API Invokes JS Callback @remoteAction global static String myMethod(String inputParam){ ... } 49. Calling Apex Remote Action Visualforce.remoting.Manager.invokeAction( {!$RemoteAction.RemoteClass.methodName}' , param, function(result, event) { //...callback to handle result }); 50. Event Object: Success Example { "statusCode":200, "type":"rpc", "ref":false, "action":"IncidentReport", "method":"createIncidentReport", "result":"a072000000pt1ZLAAY", "status":true } 51. Event Object: Failure Example { "statusCode":400, "type":"exception", "action":"IncidentReport", "method":"createIncidentReport", "message":"List has more than 1 row for assignment to SObject", "data": {"0": {"Merchandise__c":"a052000000GUgYgAAL","Type__c":"Accident","Desc ription__c":"This is an accident report"}}, "result":null, "status":false } 52. Interacting with the Publisher: Allow Submit Make Submit Active Payload true/false Sfdc.canvas.publisher.publish( { name: "publisher.setValidForSubmit", payload:true }); 53. Interacting with the Publisher: Subscribe to Submit Attach to Submit Event Sfdc.canvas.publisher.subscribe({ name: "publisher.post", onData:function(e) { // This subscribe fires when the user hits 'Submit' in the publisher postToFeed(); }}); 54. Interacting with the Publisher: Close Publisher Make the Submit Happen Sfdc.canvas.publisher.publish({name: "publisher.close", payload: { refresh:"true"}}); 55. The Future! (Well, Spring 14) 56. Remote Objects Standard CRUD/Q functionality without Apex Similar to remoteTK or SObjectData Visualforce components define data models
