Annotations

An Apex annotation modifies the way that a method or class is used, similar to annotations in Java. Annotations are defined with an initial @ symbol, followed by the appropriate keyword.

To add an annotation to a method, specify it immediately before the method or class definition. For example:

public with sharing class MyClass {
     @Future
     Public static void myMethod(String a)
     {
          //long-running Apex code
     }
}

Apex supports these annotations.

@AuraEnabled
@Deprecated
@Future
@InvocableMethod
@InvocableVariable
@IsTest
@JsonAccess
@NamespaceAccessible
@ReadOnly
@RemoteAction
@SuppressWarnings
@TestSetup
@TestVisible
Apex REST annotations:
- @ReadOnly
- @RestResource (urlMapping='/yourUrl'), where yourURL is a placeholder value
- @HttpDelete
- @HttpGet
- @HttpPatch
- @HttpPost
- @HttpPut

You can use multiple annotations for the same class or method. Specify each annotation on a separate line immediately before the class or method definition. Some annotations can’t be used together. If applicable, these limitations are documented on the page for the annotation.
