Custom Permissions

if( System.FeatureManagement.checkPermission( 
                        'ACustPerm' ) == true ) { ...


<apex:pageBlock rendered="{!$Permission.ACustPerm}" >

Custom Settings Methods

List:	List<Games__c> gamesListCustomSetting = Games__c.getAll().values();
	gamesListCustomSetting[0].GameType__c; // getAll() returns a map
	Games__c aSingleCustomSetting = Games__c.getValues( 'Pac Man' ); // same as getInstance()
Hierarchy:	Support__c supportHierarchyCustomSetting = Support__c.getInstance( profileID );
	Support__c supportHierarchyCustomSetting = Support__c.getOrgDefaults();
	Support__c supportHierarchyCustomSetting = Support__c.getValues( userID );
	// getValues doesn't merge the non-overriden values from the hierarchy
	same as {!$Setup.Support__c.Config_Field__c}

Date/DateTime Formats and Examples

myDate.format()	format() and parse() use the current user locale
myDate = Date.parse( '12/27/2009' );
myDate = Date.valueOf( '2009-12-27 23:46:00' );	uses standard datetime format
myDate.toStartMonth()
myDate.toStartWeek()

dt.format()
dt.format( 'YYYY-MM-dd hh:mm:ss.SSS a' )	2019-06-30 02:06:30.720 PM
dt.format( 'EEEEE MMMMM dd, YYYY HH:mmZ' )	Sunday June 30, 2019 14:06+0600
	z is timezone (CST), w is week in year, W is week in month, D is day in year, u is day number in week (1=Monday)
dt.getTime()	number of milisseconds since Jan 1, 1970 00:00
dt = DateTime.parse( '10/14/2011 11:46 PM' );	uses current user locale
dt = Datetime.valueOf( '2011-10-14 23:46:00' );	uses standard datetime format

Examples Using Named Credentials

HttpRequest req = new HttpRequest();
req.setEndpoint('callout:MyNamedCredential/somePath');

req.setHeader('X-Username', '{!$Credential.UserName}');
req.setHeader('X-Password', '{!$Credential.Password}');
req.setBody( 
     'UserName:{! HTMLENCODE($Credential.Username)}' );
req.setHeader( 'Authorization'
      , 'OAuth {!$Credential.OAuthToken}' );

<!-- values:  Basic, Bearer or null -->
{!$Credential.AuthorizationMethod}

<!-- values:  Base-64 encoded username and password, 
OAuth token or null -->
{!$Credential.AuthorizationHeaderValue}

{!$Credential.OAuthConsumerKey}

// usually Basic authentication goes like this instead 
of {!$Credential.AuthorizationHeaderValue}
Blob headerValue = Blob.valueOf( 
                      username + ':' + password );
String authorizationHeader = 'BASIC ' 
            + EncodingUtil.base64Encode( headerValue );
req.setHeader( 'Authorization', authorizationHeader );

Test Web Service Callouts

global class myWebServiceMockImpl 
                   implements WebServiceMock {
	global void doInvoke( Object stub
                   , Object request
                   , Map<String, Object> response
                   , String endpoint, String soapAction
                   , String requestName
                   , String responseNS
                   , String responseName
                   , String responseType ) {
	// create/populate response element and add it 
        // to the response parameter
	// this assumes responseElement type is 
        // a WSDL-generated class 
	response.put( 'response_x', responseElement );

Test.setMock( WebServiceMock.class
                   , new myWebServiceMockImpl() ); 
        // in the test class

global class myHttpCalloutMockImpl 
                   implements HttpCalloutMock {
	global HTTPResponse respond( HTTPRequest req ) {
	// create fake response, set HTTPResponse 
        // values, and return it

Test.setMock( HttpCalloutMock.class
                   , new myHttpCalloutMockImpl() );

Email Messaging

Messaging.SingleEmailMessage msg = 
               new Messaging.SingleEmailMessage();
msg.toAddresses = new String[] { 
               ...up to 100 contact/lead/user ids... };
msg.setTargetObjectId( ...single cont/lead/user id... );
msg.subject = 'Test msg';
msg.plainTextBody = 'Test body.';
Messaging.SingleEmailMessage[] msgList = 
         new List<Messaging.SingleEmailMessage> { msg };
Messaging.SendEmailResult[] results = 
         Messaging.sendEmail( msgList );

// check results[ 0 ].success 
// and results[ 0 ].errors[ 0 ].message)

Messaging.MassEmailMessage msg = 
         new Messaging.MassEmailMessage();
msg.setTargetObjectIds( 
       ...up to 250 cont/lead/user ids in List<ID>... );

String Concatenation

List<String> soqlList = new List<String> { 
        'SELECT ID, ', fieldList, ' FROM ...' };

String soql = String.join( soqlList, '' );

String Parsing with Regex

String template = '{0} was last updated {1}';
List<Object> parameters = new List<Object> {
	'Universal Containers'
        , DateTime.newInstance( 2018, 11, 15 ) };
String formatted = String.format( template, paramtrs );

Pattern ptn = Pattern.compile( 
          '...some regex with capturing groups...' );
Matcher mtr = ptn.matcher( '...input string...' );
for( Integer i = 0; i < mtr.groupCount(); i++ ) {
	// NOTE:  group 0 is the entire expression
	String extract = mtr.group( i );
}

SOQL Date Functions and Formats

CALENDAR_YEAR(), CALENDAR_MONTH()
DAY_IN_YEAR()	                    Feb 1st = 32
DAY_IN_MONTH()
DAY_IN_WEEK()	                    Sunday = 1
WEEK_IN_MONTH()
WEEK_IN_YEAR()
YESTERDAY, TODAY, TOMORROW
LAST_X, THIS_X, NEXT_X
    where X can be (where it makes sense): 
        YEAR, N_YEARS:n
        FISCAL_YEAR, N_FISCAL_YEARS:n
        FISCAL_QUARTER, N_FISCAL_QUARTERS:n
        QUARTER, N_QUARTERS:n
        MONTH, N_MONTHS:n
        90_DAYS, N_DAYS:n
        WEEK, N_WEEKS_:n

Schema Functions

Record Creation with nulls or with default values 
    and record ids

    Schema.getGlobalDescribe();
Schema.SObjectType targetType = 
    sObjTypeMap.get( typeName );
SObject sobj = targetType.newSObject();
SObject sobj = targetType.newSObject( 
    aRecordTypeId, loadDefaultsFlag );

Schema.SObjectType targetType = myObj__c.SObjectType;

myObj__c m = new myObj__c();
Schema.SObjectType targetType = m.getSObjectType();

ID Prefix
Schema.DescribeSObjectResult dscObj = descrResult[ 0 ];	
String objPrefix = dscObj.getKeyPrefix();

Schema Functions - Field Details

FieldSets
Map<String, Schema.FieldSet> fsMap = 
        dscObj.fieldSets.getMap();

Fields
Schema.DescribeFieldResult dfr = 
        dscObj.fields.myField__c;

Schema.SObjectField fieldToken = 
        mySObj__c.myField__c;
Schema.DescribeFieldResult dfr = 
        fieldToken.getDescribe();

Map<String, Schema.SObjectField> fieldMap = 
        Schema.SObjectType.mySObj__c.fields.getMap();

Field Details
dfr.getLabel(), getName(), getDefaultValue(), 
    getType(), getInlineHelpText(), ...

Picklist Values
List<Schema.PicklistEntry> pleList = 
    dfr.getPicklistValues();
// pleList[ 0 ].getLabel(), getValue(), ...

Schema Functions - Record Types

Schema.DescribeSObjectResult[] descrResult = 
	Schema.describeSObjects( new String[] { 
            'Account','Contact' } );
Schema.DescribeSObjectResult dscObj = descrResult[ 0 ];	
List<Schema.RecordTypeInfo> recTypeList = 
        dscObj.getRecordTypeInfos();
Map<Id, Schema.RecordTypeInfo> rTypeByIdMap = 
        dscObj.getRecordTypeInfosById();
Map<String, Schema.RecordTypeInfo> rTypeMap = 
        dscObj.getRecordTypeInfosByDeveloperName();
// ...getRecordTypeId() getName() getDeveloperName()

HTMLENCODE()	replaces HTML reserved characters, > becomes >
JSENCODE()	prepends escape on JS characters, ' becomes \'
JSINHTMLENCODE()	same as JSENCODE(HTMLENCODE(())
URLENCODE()	replaces illegal characters in URLs, spaces becomes %20, ? becomes %21
myString.stripHtmlTags();	removes tags from string
