EnumerableUncollect

@Deprecated
public EnumerableUncollect(RelOptCluster cluster,
 RelTraitSet traitSet,
 RelNode child)

Deprecated.

EnumerableUncollect

public EnumerableUncollect(RelOptCluster cluster,
 RelTraitSet traitSet,
 RelNode child,
 boolean withOrdinality)

Creates an EnumerableUncollect.

Use create(org.apache.calcite.plan.RelTraitSet, org.apache.calcite.rel.RelNode, boolean) unless you know what you're doing.

Method Details

create

public static EnumerableUncollect create(RelTraitSet traitSet,
 RelNode input,
 boolean withOrdinality)

Creates an EnumerableUncollect.

Each field of the input relational expression must be an array or multiset.

Parameters:

traitSet - Trait set

input - Input relational expression

withOrdinality - Whether output should contain an ORDINALITY column

copy

public EnumerableUncollect copy(RelTraitSet traitSet,
 RelNode newInput)

Overrides:

copy in class Uncollect

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
