Annotation Type DefaultMethod

@Documented @Retention(RUNTIME) @Target(PARAMETER) public @interface DefaultMethod
A parameter with this annotation is assigned an instance of Method which invokes a default method implementation of this method. If such a method is not available, this annotation causes that this delegation target cannot be bound unless nullIfImpossible() is set to true. The method is declared as public and is invokable unless the instrumented type itself is not visible. Note that requesting such a method exposes the super method to reflection.
