Method Summary

Modifier and Type	Method	Description
RelNode	copy(RelTraitSet traitSet, List<RelNode> inputs)	Creates a copy of this relational expression, perhaps changing traits and inputs.
static EnumerableValues	create(RelOptCluster cluster, RelDataType rowType, com.google.common.collect.ImmutableList<com.google.common.collect.ImmutableList<RexLiteral>> tuples)	Creates an EnumerableValues.
DeriveMode	getDeriveMode()	Returns mode of derivation.
EnumerableRel.Result	implement(EnumerableRelImplementor implementor, EnumerableRel.Prefer pref)	Creates a plan for this expression according to a calling convention.
@Nullable RelNode	passThrough(RelTraitSet required)	Pass required traitset from parent node to child nodes, returns new node after traits is passed down.

Method Details

create

public static EnumerableValues create(RelOptCluster cluster,
 RelDataType rowType,
 com.google.common.collect.ImmutableList<com.google.common.collect.ImmutableList<RexLiteral>> tuples)

Creates an EnumerableValues.

copy

public RelNode copy(RelTraitSet traitSet,
 List<RelNode> inputs)

Description copied from interface: RelNode

Creates a copy of this relational expression, perhaps changing traits and inputs.

Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.

Specified by:

copy in interface RelNode

Overrides:

copy in class AbstractRelNode

Parameters:

traitSet - Trait set

inputs - Inputs

Returns:

Copy of this relational expression, substituting traits and inputs

passThrough

public @Nullable RelNode passThrough(RelTraitSet required)

Description copied from interface: PhysicalNode

Pass required traitset from parent node to child nodes, returns new node after traits is passed down.

Specified by:

passThrough in interface PhysicalNode

getDeriveMode

public DeriveMode getDeriveMode()

Description copied from interface: PhysicalNode

Returns mode of derivation.

Specified by:

getDeriveMode in interface EnumerableRel

Specified by:

getDeriveMode in interface PhysicalNode

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 interface EnumerableRel

Parameters:

implementor - Implementor

pref - Preferred representation for rows in result expression

Returns:

Plan for this expression according to a calling convention
