org.apache.pig.newplan.optimizer.Transformer.check()
check if the transform should be done. If this is being called then the pattern matches, but there may be other criteria that must be met as well. @param matched the sub-set of the plan that matches the pattern. This subset has the same graph as the pattern, but the operators point to the same objects as the plan to be matched. @return true if the transform should be done. @throws Transformer
