Annotation Type ReceiverMethod

@Retention(value=CLASS)
 @Target(value=METHOD)
public @interface ReceiverMethod

The ReceiverMethod allows you to provide a custom method implementation in the generated type but still generate the over the boundary call. It's useful when pre-code or post-code is needed before or after over the boundary call. The annotated method must have the same parameter types as the receiver method. Example showing a method execute with custom pre-code and post-code.

 @Override
 public final boolean execute() {
     preCode();
     boolean result = executeImpl();
     postCode();
     return result;
 }

 @ReceiverMethod("execute")
 abstract boolean executeImpl();
