Uses of AbstractPhysicalVisitor in org.apache.drill.exec.planner.fragment.contrib

Subclasses of AbstractPhysicalVisitor in org.apache.drill.exec.planner.fragment.contrib

Modifier and Type	Class	Description
class	ExchangeRemoverMaterializer	Materializer visitor to remove exchange(s) NOTE: this Visitor does NOT set OperatorId, as after Exchange removal all operators need renumbering Use OperatorIdVisitor on top to set correct OperatorId
class	OperatorIdVisitor	Visitor to renumber operators - needed after materialization is done as some operators may be removed using @ExtendedMaterializerVisitor
