public class Aspects14 extends java.lang.Object
For users working on a level of Java prior to Java5, Aspects14 handles generic aspectOf methods when they are not available in the aspects but added later on through load time weaving. Users on Java5 should use the class Aspects instead. Aspects14.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.
