Class InterceptorChain

java.lang.Object

org.proxy4j.core.InterceptorChain

All Implemented Interfaces:

org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor

public class InterceptorChain
extends Object
implements org.aopalliance.intercept.MethodInterceptor

An adaptation of Guice's InterceptorStackCallback (author: Bob Lee), but generalized to use the AOP alliance interfaces. This class is used to hold a chain of MethodInterceptors, which are invoked in order by the proxy. Any interceptor that does not call MethodInvocation#proceed() will effectively short-circuit the traversal of the chain and prevent the target from being called.
