Constructor Detail

ElasticsearchFilter

ElasticsearchFilter(RelOptCluster cluster,
                    RelTraitSet traitSet,
                    RelNode child,
                    RexNode condition)

Method Detail

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 Filter

Parameters:

planner - Planner for cost calculation

mq - Metadata query

Returns:

Cost of this plan (not including children)

copy

public Filter copy(RelTraitSet relTraitSet,
                   RelNode input,
                   RexNode condition)

Specified by:

copy in class Filter

implement

public void implement(ElasticsearchRel.Implementor implementor)

Specified by:

implement in interface ElasticsearchRel
