Annotation Interface Introduction

@Documented @Retention(RUNTIME) @Target({ANNOTATION_TYPE,TYPE}) @InterceptorBinding(kind=INTRODUCTION) public @interface Introduction

Introduction advice allows interfaces and abstract classes to be implemented at compile time by MethodInterceptor implementations.

This annotation should be applied as a meta annotation to another annotation that references the MethodInterceptor by type

For example:


  @Introduction
  @Type(ExampleIntroduction.class)
  @Documented
  @Retention(RUNTIME)
   public @interface Example {
   }

Note that the annotation MUST be RetentionPolicy.RUNTIME and the specified Type must implement MethodInterceptor
