Method Detail

copy

public Bindables.BindableAggregate copy(RelTraitSet traitSet,
                               RelNode input,
                               boolean indicator,

                               List<AggregateCall> aggCalls)

Description copied from class: Aggregate

Creates a copy of this aggregate.

Specified by:

copy in class Aggregate

Parameters:

traitSet - Traits

input - Input

indicator - Whether row type should include indicator fields to indicate which grouping set is active; must be true if aggregate is not simple

groupSet - Bit set of grouping fields

groupSets - List of all grouping sets; null for just groupSet

aggCalls - Collection of calls to aggregate functions

Returns:

New Aggregate if any parameter differs from the value of this Aggregate, or just this if all the parameters are the same

Aggregate.copy(org.apache.calcite.plan.RelTraitSet, java.util.List)

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
