Re: [aspectj-users] A question about pointcut
|
Does this help?:
aspect A {
before(): call(* *(..)) && !within(A) {
Object[] lArgs;
lArgs = thisJoinPoint.getArgs();
for(int lCounter = 0;
lCounter<lArgs.length;
lCounter++){
if(lArgs[lCounter] instanceof java.lang.String){
System.out.println(lArgs[lCounter]);
} }
}
}
this matches every method signature, except the calls within the aspect. if
you don't do this you will have an infinite loop when you call println, the
pointcut is matched, and will call println, and on , and on.
Now you can check the args for their type.. I can't seem to find a way to
only specify matching during the pointcut of one or more paramaters, and
that have a specific type... Have you found a different way yet?

Consider the scenario that I want to define a generic advice to check the
string encoding of all string arguments of all methods. How would I write
my code? Can anyone shed some light? Thanks.
