Method Detail

copy

public EnumerableAggregate copy(RelTraitSet traitSet,
                       RelNode input,
                       boolean indicator,
                       ImmutableBitSet groupSet,
                       List<ImmutableBitSet> groupSets,
                       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)

implement

public EnumerableRel.Result implement(EnumerableRelImplementor implementor,
                             EnumerableRel.Prefer pref)

Description copied from interface: EnumerableRel

Creates a plan for this expression according to a calling convention.

Specified by:

implement in interface EnumerableRel

Parameters:

implementor - Implementor

pref - Preferred representation for rows in result expression

Returns:

Plan for this expression according to a calling convention
