Hi Bhaskar and Mohan,
I think Bhaskar is trying to access method NAMES, not actual values. You can
access method names in AspectJ, using MethodSignature.getParameterNames ..
for example:
void around() : test(){
Signature s = thisJoinPointStaticPart.getSignature();
// Warning, this means you are weaving a method, otherwise there will be
of another subclass of Signature
MethodSignature m = (MethodSignature)s;
String[] names = m.getParameterName();
Object[] values = thisJoinPoint.getArgs();
for (int i = 0; i < names.length; i++) {
System.out.println(names[i] + " : " + values[i]);
}
proceed();
}
Names are present only if target code (the class you are weaving) has been
compiled with debug symbols, which is true for 99% of java code actually
available, but still could happen that you are weaving into a third party
library which has been compiled without debug symbols.
