  org.apache.webbeans.component.AbstractOwbBean<T>
      org.apache.webbeans.intercept.webbeans.WebBeansInterceptor<T>

All Implemented Interfaces:

javax.enterprise.context.spi.Contextual<T>, javax.enterprise.inject.spi.Bean<T>, javax.enterprise.inject.spi.Interceptor<T>, OwbBean<T>, OwbInterceptor<T>

Direct Known Subclasses:

CustomInterceptor

public class WebBeansInterceptor<T>
extends AbstractOwbBean<T>
implements OwbInterceptor<T>

Defines the webbeans specific interceptors.

WebBeans interceotor classes has at least one InterceptorBinding annotation. It can be defined on the class or method level at the component. WebBeans interceptors are called after the EJB related interceptors are called in the chain. Semantics of the interceptors are specified by the EJB specificatin.
