      • hasSideEffects

        public boolean hasSideEffects()

      • resetTargets

        public void resetTargets()
        Recursively unlabel every TARGET or YIELD node in the tree. This is used and should only be used for inlining finally blocks where jsr instructions used to be. It is somewhat hackish, but implementing a clone() operation would take much, much more effort. This solution works for inlining finally blocks because you should never be writing any given block to the class file simultaneously. Therefore, an unlabeling will never occur in the middle of a block.
