Method Detail

isBeforeAdvice

public boolean isBeforeAdvice()

Description copied from interface: AspectJPrecedenceInformation

Return whether this is a before advice.

Specified by:

isBeforeAdvice in interface AspectJPrecedenceInformation

isAfterAdvice

public boolean isAfterAdvice()

Description copied from interface: AspectJPrecedenceInformation

Return whether this is an after advice.

Specified by:

isAfterAdvice in interface AspectJPrecedenceInformation

supportsProceedingJoinPoint

protected boolean supportsProceedingJoinPoint()

Overrides:

supportsProceedingJoinPoint in class AbstractAspectJAdvice

invoke

public Object invoke(MethodInvocation mi)
              throws Throwable

Description copied from interface: MethodInterceptor

Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().

Specified by:

invoke in interface MethodInterceptor

Parameters:

mi - the method invocation joinpoint

Returns:

the result of the call to {@link Joinpoint#proceed(); might be intercepted by the interceptor

Throws:

Throwable - if the interceptors or the target object throws an exception

lazyGetProceedingJoinPoint

protected org.aspectj.lang.ProceedingJoinPoint lazyGetProceedingJoinPoint(ProxyMethodInvocation rmi)

Return the ProceedingJoinPoint for the current invocation, instantiating it lazily if it hasn't been bound to the thread already.

Parameters:

rmi - the current Spring AOP ReflectiveMethodInvocation, which we'll use for attribute binding

Returns:

the ProceedingJoinPoint to make available to advice methods
