Re: [aspectj-users] Accessing value of annotation on method parameter
|
Hi Luke,
This is enhancement
https://bugs.eclipse.org/bugs/show_bug.cgi?id=259416 - currently you
cannot do it directly in the syntax, you need to dig them out of the
thisJoinPoint object.
MethodSignature ms =
(MethodSignature)thisJoinPointStaticPart.getSignature();
System.out.println(ms.getMethod().getParameterAnnotations()[0][0]);
when it is supported, likely syntax is:
before(SomeAnno anno): execution(* someMethod(..)) && @args(anno (*)) {}
cheers,
Andy
