[aspectj-users] RE: around advice will weave pointcut ?

[Ramnivas Laddad <ramnivas@xxxxxxxxx>]

Rice,

Just pass all the the arguments captured in around() 
advice to the proceed() statement -- proceed(event, guard).

The type and number of argument to the advised method 
need not match with proceed(). Only the context collected 
by the around() advice need to match in type and number 
to the arguments passed to proceed().
