Method Detail

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

computeSelfCost

public RelOptCost computeSelfCost(RelOptPlanner planner)

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 interface RelNode

Overrides:

computeSelfCost in class Window

Parameters:

planner - Planner for cost calculation

Returns:

Cost of this plan (not including children)

getElementType

public Class<Object[]> getElementType()

Description copied from interface: Typed

Gets the type of the element(s) that are returned in this collection.

Specified by:

getElementType in interface ArrayBindable

Specified by:

getElementType in interface Typed

bind

public Enumerable<Object[]> bind(DataContext dataContext)

Description copied from interface: Bindable

Executes this statement and returns an enumerable which will yield rows. The environment parameter provides the values in the root of the environment (usually schemas).

Specified by:

bind in interface Bindable<Object[]>

Parameters:

dataContext - Environment that provides tables

Returns:

Enumerable over rows

implement

public Node implement(InterpretableRel.InterpreterImplementor implementor)

Description copied from interface: InterpretableRel

Creates an interpreter node to implement this relational expression.

Specified by:

implement in interface InterpretableRel
