Examples of org.aspectj.weaver.ShadowMunger

org.aspectj.weaver.ShadowMunger
For every shadow munger, nothing can be done with it until it is concretized. Then... (Then we call fast match.) For every shadow munger, for every shadow, first match is called, then (if match returned true) the shadow munger is specialized for the shadow, which may modify state. Then implement is called.

            world.getLint().adviceDidNotMatch.isEnabled()) {
          List l = world.getCrosscuttingMembersSet().getShadowMungers();
          Set alreadyWarnedLocations = new HashSet();
          
          for (Iterator iter = l.iterator(); iter.hasNext();) {
            ShadowMunger element = (ShadowMunger) iter.next();
            if (element instanceof BcelAdvice) { // This will stop us incorrectly reporting deow Checkers
                  BcelAdvice ba = (BcelAdvice)element;
                  if (!ba.hasMatchedSomething()) {
           // Because we implement some features of AJ itself by creating our own kind of mungers, you sometimes
              // find that ba.getSignature() is not a BcelMethod - for example it might be a cflow entry munger.
                   if (ba.getSignature()!=null) {
                     
                     // check we haven't already warned on this advice and line
                     // (cflow creates multiple mungers for the same advice)
                     AdviceLocation loc = new AdviceLocation(ba);
                     if (alreadyWarnedLocations.contains(loc)) {
                       continue;
                     } else {
                       alreadyWarnedLocations.add(loc);
                     }
                     
             if (!(ba.getSignature() instanceof BcelMethod)
                 || !Utility.isSuppressing((AnnotationX[])ba.getSignature().getAnnotations(),"adviceDidNotMatch")) {
