Method Details

create

public static LogicalRepeatUnion create(RelNode seed,
 RelNode iterative,
 boolean all,
 @Nullable RelOptTable transientTable)

Creates a LogicalRepeatUnion.

create

public static LogicalRepeatUnion create(RelNode seed,
 RelNode iterative,
 boolean all,
 int iterationLimit,
 @Nullable RelOptTable transientTable)

Creates a LogicalRepeatUnion.

copy

public LogicalRepeatUnion copy(RelTraitSet traitSet,
 List<RelNode> inputs)

Description copied from interface: RelNode

Creates a copy of this relational expression, perhaps changing traits and inputs.

Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.

Specified by:

copy in interface RelNode

Overrides:

copy in class AbstractRelNode

Parameters:

traitSet - Trait set

inputs - Inputs

Returns:

Copy of this relational expression, substituting traits and inputs

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
