Re: [aspectj-users] Method parameters
|
Nils,
You could use thisEnclosingJoinPointStaticPart to determine the types of these arguments, but you can't access their values directly in advice on another JP. You probably can still use AJ to achieve the same effect by coordinating 2 pieces of advice. Might use advice on the execution join point to either capture the values in advance (with before advice) or defer the "real work" to after returning or after throwing on the execution, and use some mechanism to coordinate the handler advice with the execution advice.

> I was wondering if it is possible to get information about method parameters within an advice. I know I can use the thisJoinPoint.getArgs() to get this information in a call() pointcut, but when using a handler() pointcut, getArgs() will only give me the information about the exception that was caught, not the parameters that was passed into the method where the catch block is.
