Method Detail

copy

public Bindables.BindableJoin copy(RelTraitSet traitSet,
                                   RexNode conditionExpr,
                                   RelNode left,

                                   boolean semiJoinDone)

Description copied from class: Join

Creates a copy of this join, overriding condition, system fields and inputs.

General contract as RelNode.copy(org.apache.calcite.plan.RelTraitSet, java.util.List<org.apache.calcite.rel.RelNode>).

Specified by:

copy in class Join

Parameters:

traitSet - Traits

conditionExpr - Condition

left - Left input

right - Right input

joinType - Join type

semiJoinDone - Whether this join has been translated to a semi-join

Returns:

Copy of this join

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

public Enumerable<Object[]> bind(DataContext dataContext)

Description copied from interface: Bindable

Executes this statement and returns an enumerable which will yield rows. The environment parameter provides the values in the root of the environment (usually schemas).

Specified by:

bind in interface Bindable<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
