Re: [aspectj-users] getting the object from a joinpoint

[Paulo Alexandre Corigo Zenida <paulo.zenida@xxxxxxxx>]

Hello,

	Try the following:

	before() :
		call(*.new(..)) &&
		!within(CaptureClassTypeAspect) {
		Class c = thisJoinPoint.getSignature().getDeclaringType();
		if (c.equals(A.class)) {
			System.out.println("The class is an instance of A");
		} else {
			System.out.println("The class is not an instance of A");
		}
	}


	I hope this will help. Best regards,

		Paulo Zenida
