Class IsolatedForwardingInterceptor<T>

java.lang.Object

org.jboss.weld.util.bean.ForwardingBeanAttributes<T>

org.jboss.weld.util.bean.IsolatedForwardingBean<T>

org.jboss.weld.util.bean.IsolatedForwardingInterceptor<T>

All Implemented Interfaces:

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

Direct Known Subclasses:

ForwardingInterceptor, IsolatedForwardingInterceptor.Impl

public abstract class IsolatedForwardingInterceptor<T>
extends IsolatedForwardingBean<T>
implements Interceptor<T>

Delegating implementation of Interceptor. Separate delegate is used for BeanAttributes methods, allowing this class to be used for processing of extension-provided beans.
