Method Details
-
create
public static EnumerableHashJoin create(RelNode left, RelNode right, RexNode condition, Set<CorrelationId> variablesSet, JoinRelType joinType) Creates an EnumerableHashJoin. -
copy
public EnumerableHashJoin copy(RelTraitSet traitSet, RexNode condition, RelNode left, RelNode right, JoinRelType joinType, boolean semiJoinDone) Description copied from class:Join
Creates a copy of this join, overriding condition, system fields and inputs.General contract as
RelNode.copy(org.apache.calcite.plan.RelTraitSet, java.util.List<org.apache.calcite.rel.RelNode>)
. -
passThroughTraits
Description copied from interface:PhysicalNode
Pass required traitset from parent node to child nodes, returns a pair of traits after traits is passed down.Pair.left: the new traitset; Pair.right: the list of required traitsets for child nodes.
- Specified by:
passThroughTraits
in interfaceEnumerableRel
- Specified by:

in interfacePhysicalNode
-
deriveTraits
public @Nullable Pair<RelTraitSet,List<RelTraitSet>> deriveTraits(RelTraitSet childTraits, int childId) Description copied from interface:PhysicalNode
Derive traitset from child node, returns a pair of traits after traits derivation.Pair.left: the new traitset; Pair.right: the list of required traitsets for child nodes.
- Specified by:
deriveTraits
in interfaceEnumerableRel
- Specified by:

getDeriveMode
Description copied from interface:PhysicalNode
Returns mode of derivation.- Specified by:
getDeriveMode
in interfaceEnumerableRel
- Specified by:
getDeriveMode
in interfacePhysicalNode
-
computeSelfCost
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 classJoin
- Parameters:
planner
- Planner for cost calculationmq
- Metadata query- Returns:
- Cost of this plan (not including children)
-
implement
public EnumerableRel.Result implement(EnumerableRelImplementor implementor, EnumerableRel.Prefer pref) Description copied from interface:EnumerableRel
Creates a plan for this expression according to a calling convention.- Specified by:
implement
in interfaceEnumerableRel
- Parameters:
implementor
- Implementorpref
- Preferred representation for rows in result expression- Returns:
- Plan for this expression according to a calling convention
