Constructor Details

LogicalDelta

public LogicalDelta(RelOptCluster cluster,
 RelTraitSet traits,
 RelNode input)

Creates a LogicalDelta.

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

Parameters:

cluster - Cluster that this relational expression belongs to

input - Input relational expression

LogicalDelta

public LogicalDelta(RelInput input)

Creates a LogicalDelta by parsing serialized output.

Method Details

create

public static LogicalDelta create(RelNode input)

Creates a LogicalDelta.

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
