Class RelationalPlanner

java.lang.Object
  org.teiid.query.optimizer.relational.RelationalPlanner

public class RelationalPlanner
extends java.lang.Object

This class generates a relational plan for query execution. The output of this class is a PlanNode object - this object then becomes the input to PlanToProcessConverter to produce a RelationalPlan.
