Constructor Detail

GeodeSort

GeodeSort(RelOptCluster cluster,
          RelTraitSet traitSet,
          RelNode input,
          RelCollation collation,
          RexNode fetch)

Creates a GeodeSort.

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 Sort

Parameters:

planner - Planner for cost calculation

mq - Metadata query

Returns:

Cost of this plan (not including children)

copy

public Sort copy(RelTraitSet traitSet,
                 RelNode input,
                 RelCollation newCollation,
                 RexNode offset,
                 RexNode fetch)

Specified by:

copy in class Sort

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

fieldName

private java.lang.String fieldName(int index)

direction

private java.lang.String direction(RelFieldCollation.Direction relDirection)
