Method Detail

invokeNextInterceptor

public java.lang.Object invokeNextInterceptor(InvocationContext invocationContext)
                                       throws java.lang.Exception

Description copied from interface: InterceptionChain

Specified by:

invokeNextInterceptor in interface InterceptionChain

Parameters:

invocationContext - the invocation context to be passed to the interceptor method

Returns:

the value returned by the interceptor

Throws:

java.lang.Exception

invokeNext

protected java.lang.Object invokeNext(InvocationContext invocationContext)
                               throws java.lang.Exception

Throws:

java.lang.Exception

interceptorChainCompleted

protected abstract java.lang.Object interceptorChainCompleted(InvocationContext invocationContext)
                                                       throws java.lang.Exception

Throws:

java.lang.Exception

hasNextInterceptor

public boolean hasNextInterceptor()

Description copied from interface: InterceptionChain

Indicates whether there are not-yet-invoked interceptor methods in the chain.

Specified by:

hasNextInterceptor in interface InterceptionChain

Returns:
