LogicalIntersect

public LogicalIntersect(RelInput input)

Creates a LogicalIntersect by parsing serialized output.

Method Detail

create

public static LogicalIntersect create(List<RelNode> inputs,
                                      boolean all)

Creates a LogicalIntersect.

copy

public LogicalIntersect copy(RelTraitSet traitSet,
                             List<RelNode> inputs,
                             boolean all)

Specified by:

copy in class SetOp

accept

public RelNode accept(RelShuttle shuttle)

Description copied from interface: RelNode

Accepts a visit from a shuttle.

Specified by:

accept in interface RelNode

Overrides:

accept in class AbstractRelNode

Parameters:

shuttle - Shuttle

Returns:

A copy of this node incorporating changes made by the shuttle to this node's children

withHints

public RelNode withHints(List<RelHint> hintList)

Description copied from interface: Hintable

Returns a new relational expression with the specified hints hintList.

This method should be overridden by every logical node that supports hint. It is only for internal use during decorrelation.

Sub-class should return a new copy of the relational expression.

The default implementation returns the relational expression directly only because not every kind of relational expression supports hints.

Returns:

Relational expression with set up hints
