All aspects are added to the - * world, by calling addOrReplaceAspect on - * the crosscutting members set of the world. When aspects are added or - * replaced, the crosscutting members in the aspect are extracted as - * ShadowMungers (each holding a pointcut). The ShadowMungers are - * concretized, which concretizes the pointcuts. At this stage - * ReferencePointcuts are replaced by their declared content. - * - * During weaving, the weaver processes type by type. It first culls - * potentially matching ShadowMungers by calling the fastMatch method - * on their pointcuts. Only those that might match make it through to - * the next phase. At the next phase, all of the shadows within the - * type are created and passed to the pointcut for matching (match). - * - * When the actual munging happens, matched pointcuts are asked for - * their residue (findResidue) - the runtime test if any.
