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:

Apex supports these annotations.

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.
