All Implemented Interfaces:

Contextual<T>, Bean<T>, Interceptor<T>, PassivationCapable, OwbBean<T>, BeanAttributes<T>

Direct Known Subclasses:

CdiInterceptorBean, EjbInterceptorBean, SelfInterceptorBean

public abstract class InterceptorBean<T>
extends InjectionTargetBean<T>
implements Interceptor<T>

Abstract Interceptor Bean implementation.

Any Interceptor is also an InjectionTarget as they can contain @Inject InjectionPoints.
