Method Detail

copy
public Project copy(RelTraitSet traitSet, RelNode input, java.util.List<RexNode> projects, RelDataType rowType)
Description copied from class:Project
Copies a project.- Specified by:
copy
in classProject
- Parameters:
traitSet
- Traitsinput
- Inputprojects
- Project expressionsrowType
- Output row type- Returns:
- New
Project
if any parameter differs from the value of thisProject
, or justthis
if all the parameters are the same - See Also:
Project.copy(RelTraitSet, 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 interfaceRelNode
- Overrides:
computeSelfCost
in classProject
- Parameters:
planner
- Planner for cost calculationmq
- 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 theGeodeRel
required to convert the relational tree into physical such.
