org.apache.pig.experimental.plan.optimizer.Rule.match()
Search for all the sub-plans that matches the pattern defined by this rule. @return A list of all matched sub-plans. The returned plans arepartial views of the original OperatorPlan. Each is a sub-set of the original plan and represents the same topology as the pattern, but operators in the returned plan are the same objects as the original plan. Therefore, a call getPlan() from any node in the return plan would return the original plan. @param plan the OperatorPlan to look for matches to the pattern

        pattern.add(s3);
        pattern.connect(s1, s2);
        pattern.connect(s1, s3);
        
        r = new SillyRule("basic", pattern);
        l = r.match(plan);
        assertEquals(1, l.size());
        
        assertEquals(l.get(0).getSources().size(), 1);
        assertEquals(l.get(0).getSinks().size(), 2);
        assertEquals(l.get(0).size(), 3);
