Interface AnnotationReplacer<T extends java.lang.annotation.Annotation>

Type Parameters:

T -

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface AnnotationReplacer<T extends java.lang.annotation.Annotation>

An interface that allows creating annotations that will get replaced by others.

This can be exceptionally powerful (and dangerous), as it can create dynamic annotations, whose values are not restricted by static, compile-time known ones.

It also allows building shortcut annotations, as well as configurable values inside annotations.

Register with Lamp.Builder.annotationReplacer(Class, AnnotationReplacer)
