Class RelMdPopulationSize

java.lang.Object

org.apache.calcite.rel.metadata.RelMdPopulationSize

All Implemented Interfaces:

MetadataHandler<BuiltInMetadata.PopulationSize>

public class RelMdPopulationSize
extends Object
implements MetadataHandler<BuiltInMetadata.PopulationSize>

RelMdPopulationSize supplies a default implementation of RelMetadataQuery.getPopulationSize(org.apache.calcite.rel.RelNode, org.apache.calcite.util.ImmutableBitSet) for the standard logical algebra.
