Method Details

copy

public Bindables.BindableUnion copy(RelTraitSet traitSet,
 List<RelNode> inputs,
 boolean all)

Specified by:

copy in class SetOp

getElementType

public Class<Object[]> getElementType()

Description copied from interface: Typed

Gets the type of the element(s) that are returned in this collection.

Specified by:

getElementType in interface ArrayBindable

Specified by:

getElementType in interface Typed

bind

bind in interface Bindable<@Nullable Object[]>

Parameters:

dataContext - Environment that provides tables

Returns:

Enumerable over rows

implement

public Node implement(InterpretableRel.InterpreterImplementor implementor)

Description copied from interface: InterpretableRel

Creates an interpreter node to implement this relational expression.

Specified by:

implement in interface InterpretableRel
