Common Use Cases

Email Templates

Mobile Interfaces

Generate PDFs

Page Overrides

Visualforce Controllers
Apex for constructing dynamic pages

Viewstate
Hashed information block to track server side transports

Reducing Viewstate
//Transient data that does not get sent back,
//reduces viewstate
transient String userName {get; set;}
//Static and/or private vars
//also do not become part of the viewstate
static private integer VERSION_NUMBER = 1;

Reducing Viewstate
//Asynchronous JavaScript callback. No viewstate.
//RemoteAction is static, so has no access to Controller context
@RemoteAction
public 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 parameter
if(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 page
return null;

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

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

Unit Testing Pages
//Set test page
Test.setCurrentPage(Page.VisualforcePage);
//Set test data
Account a = new Account(Name='TestCo');
insert a;
//Set test params
ApexPages.currentPage().getParameters().put('id',a.Id);
//Instatiate Controller
SomeController controller = new SomeController();

//Make assertion
System.assertEquals(controller.AccountId,a.Id)

Apex Triggers
Event 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 Apex
Cron-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

Via Apex

Via Web UI

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

Batch Apex
Functionality 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();

OAuth
Industry standard method of user authentication

OAuth2 Flow

Sends App Credentials
User logs in,
Token sent to callback

Remote
Application

Confirms token

Send access token

Maintain session with
refresh token

Apex Endpoints
Exposing 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 Email
Classes 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 label
mail.setToAddresses(Label.emaillist.split(','));
mail.setSubject ('[Warehouse] Dated Invoices');
mail.setPlainTextBody(body);
//Send the email
Messaging.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
