Examples of POProject

org.apache.pig.backend.hadoop.executionengine.physicalLayer.expressionOperators.POProject
Implements the overloaded form of the project operator. Projects the specified column from the input tuple. However, if asked for tuples when the input is a bag, the overloaded form is invoked and the project streams the tuples through instead of the bag.

            Tuple t = tf.newTuple();
            t.append(r.nextFloat());
            bag.add(t);
        }
        
        POProject prj = new POProject(new OperatorKey("", r.nextLong()), -1, 0);
        prj.setResultType(DataType.FLOAT);
        PONegative pn = new PONegative(new OperatorKey("", r.nextLong()), -1, prj);
        pn.setResultType(DataType.FLOAT);
        
        PhysicalPlan plan = new PhysicalPlan();
        plan.add(prj); plan.add(pn);
