Package react4j.annotations

Annotation Interface PostUpdate

@Documented @Target(METHOD) public @interface PostUpdate
Identifies a method that is called after a view is updated or re-rendered. Re-render in this circumstance means that a view has been mounted on the DOM and changes to the view are being applied to the dom. There must only be one method annotated with this annotation in a view. This method is invoked in the "commit" phase using reacts componentDidUpdate() lifecycle method.

The method must also conform to the following constraints:

  • Must not be annotated with any other react4j annotation
  • Must have 0 parameters
  • Must not return a value
  • Must not be private
  • Must not be public
  • Must not be static
  • Must not be abstract
  • Must not throw exceptions
  • Must be accessible from the same package as the class annotated by View
  • Should not be public as not expected to be invoked outside the view. A warning will be generated but can be suppressed by the SuppressWarnings or SuppressReact4jWarnings annotations with a key "React4j:PublicMethod". This warning is also suppressed by the annotation processor if it is implementing an interface method.
  • Should not be protected if in the class annotated with the View annotation as the method is not expected to be invoked outside the view. A warning will be generated but can be suppressed by the SuppressWarnings or SuppressReact4jWarnings annotations with a key "React4j:ProtectedMethod".
