Examples of org.apache.pig.newplan.OperatorSubPlan

org.apache.pig.newplan.OperatorSubPlan
Class to represent a view of a plan. The view contains a subset of the plan. All the operators returned from the view are the same objects to the operators in its base plan. It is used to represent match results.
