Class Aspects

java.lang.Object
  org.aspectj.lang.Aspects

public class Aspects
extends java.lang.Object

Handles generic aspectOf method when those are not available in the aspects but added later on thru load time weaving.

Aspects.aspectOf(..) is doing reflective calls to the aspect aspectOf, so for better performance consider using ajc compilation of the aspects and using them as a binary dependancies in your project.
