Re: [aspectj-users] Which field is being accessed

[Dean Wampler <dean@xxxxxxxxxxxxxxxxxxxxx>]

You have to use the AspectJ reflection API. Here's a snippet of code  
from Contract4J (InvariantFieldConditions.aj, to be specific). This  
would appear in your advice:

		Signature sig = thisJoinPoint.getSignature();
		String fieldName     = sig.getName();
		Class<?> clazz       = sig.getDeclaringType();
		SourceLocation loc   = thisJoinPoint.getSourceLocation();
		// Get the "old" value of the field.
		Field  field        = ((FieldSignature) sig).getField();
		Class<?> fieldClass = field.getType();

H.T.H.
