Annotation Type DefaultMethodHandle

@Documented
 @Retention(value=RUNTIME)
 @Target(value=PARAMETER)
public @interface DefaultMethodHandle

A parameter with this annotation is assigned an instance of java.lang.invoke.MethodHandle 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. Note that requesting such a method exposes the default method to reflective access.
