Many people say that AOP is an interceptor, pointcut expression, aspect and implementation (advices). Actually AOP
More than that, another important feature in JBoss AOP is the ability to transparently pass interfaces to Java classes. You
You can enforce an interface implemented by a class, and you can even attach another class (mixins) to implement this interface. Just like C + +
