Annotations

Annotations:
* An Apex annotation modifies the way 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. global class MyClass {      @future      Public static void myMethod(String a)      {           //long-running Apex code          } }
Annotations supported by Apex
Annotation Name	Description
@Deprecated	* Use the deprecated annotation to identify methods, classes, exceptions, enums, interfaces or variables that can no longer be referenced in subsequent release of the managed package in which they reside. * This is useful when you are refactoring code in managed package as the requirements evolve. * New subscribers cannot see the deprecated elements, while the elements continue to function for existing subscribers and API integrations. Syntax: @deprecated //This method is deprecated, use myOptimizedMethod(String a, String b) instead Public void myMethod(String a) { }
