RE: [aspectj-users] Matching methods with a particular argument type

["David Hatton \(AT/LMI\)" <david.hatton@xxxxxxxxxxxx>]

Hi again,

 

We're getting this to work:

 

pointcut bcMethodsTransactionAfterMethods(Transaction tx):
   (execution (!private * com.ericsson.nms.cif.cs.*.*(.., Transaction)) && args(.., tx) );

 

before(Transaction tx): bcMethodsTransactionBeforeMethods(tx) {
   CsTrace.traceTransaction(
      thisJoinPointStaticPart.getSignature().getDeclaringTypeName(),
      thisJoinPointStaticPart.getSignature().getName(),
      thisJoinPoint.getArgs(),
      tx);
}

 

But it doesn't seem to work when the Transaction object is null? Is that expected?

 

/David

One can use .. in the front and the back in method patterns (more than once).

But you get a compilation error when using more than one .. in

args pointcut designators. This is a compiler limitation because of ambiguousness

in the binding.

And a 

before(): execution(* *.*(.., String, ..)) {

}

public class SignatureTest {

public void test(String arg) {

}

}

will match the SignatureTest.test(String).

And a 

before(String arg): execution(* *.*(.., String, ..)) && args(.., args, ...) {

} 

will cause a compilation error: uses more than one .. in args (compiler limitation)

No, I think think this is even syntactically wrong cause you cannot

have ".." both in the front and back. IMHO there is no way to match on

methods which have a String parameter at an arbitrary place (without

using reflection at least).

Hi,

Would the last case match:

   com.ericsson.nms.cif.cs.Aclass.Amethod(String something); ???

my 2 cents here.

Not in my opinion...

It will match any methods which have 3 parameters  in which the second one is a String.....

anyone could correct me if i m wrong?
