Constructor Detail

GeodeAggregate

public GeodeAggregate(RelOptCluster cluster,
                      RelTraitSet traitSet,
                      RelNode input,
                      boolean indicator,
                      ImmutableBitSet groupSet,
                      java.util.List<ImmutableBitSet> groupSets,
                      java.util.List<AggregateCall> aggCalls)

Creates a GeodeAggregate.

Method Detail

copy

public Aggregate copy(RelTraitSet traitSet,
                      RelNode input,
                      boolean indicator,
                      ImmutableBitSet groupSet,
                      java.util.List<ImmutableBitSet> groupSets,
                      java.util.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)

computeSelfCost

public RelOptCost computeSelfCost(RelOptPlanner planner,
                                  RelMetadataQuery mq)

Description copied from interface: RelNode

Returns the cost of this plan (not including children). The base implementation throws an error; derived classes should override.

NOTE jvs 29-Mar-2006: Don't call this method directly. Instead, use RelMetadataQuery.getNonCumulativeCost(org.apache.calcite.rel.RelNode), which gives plugins a chance to override the rel's default ideas about cost.

Specified by:

computeSelfCost in interface RelNode

Overrides:

computeSelfCost in class Aggregate

Parameters:

planner - Planner for cost calculation

mq - Metadata query

Returns:

Cost of this plan (not including children)

implement

public void implement(GeodeRel.GeodeImplementContext geodeImplementContext)

Description copied from interface: GeodeRel

Callback for the implementation process that collects the context from the GeodeRel required to convert the relational tree into physical such.

Specified by:

implement in interface GeodeRel

Parameters:

geodeImplementContext - Context class that collects the feedback from the call back method calls

fieldNames

private java.util.List<java.lang.String> fieldNames(RelDataType relDataType)
