@Documented
 @Target(value=METHOD)
public @interface OnPropChanged

Identifies a method that is called when the prop value is changed and after the component has rendered. This method is invoked from the Component.shouldComponentUpdate(JsPropertyMap) lifecycle method. The method may be defined with one parameter which is the old value of the prop. The method can also have zero parameters if the component author just wants to be notified when the prop is changed.

The method must also conform to the following constraints:

• Must not be annotated with any other react4j annotation
• Must have either 0 or 1 parameters. If present the parameter must match the type of the prop
• 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 ReactComponent
