Interface RelRule.OperandDetailBuilder<R extends RelNode>

Type Parameters:

R - Type of relational expression

Enclosing class:

RelRule<C extends RelRule.Config>

public static interface RelRule.OperandDetailBuilder<R extends RelNode>

Add details about an operand, such as its inputs.

Method Summary

Modifier and Type	Method	Description
RelRule.Done	anyInputs()	Indicates that this operand takes any number or type of inputs.
RelRule.Done	convert(RelTrait in)	Indicates that this operand converts a relational expression to another trait.
RelRule.Done	inputs(RelRule.OperandTransform... transforms)	Indicates that this operand has several inputs.
RelRule.Done	noInputs()	Indicates that this operand takes no inputs.
RelRule.Done	oneInput(RelRule.OperandTransform transform)	Indicates that this operand has a single input.
RelRule.OperandDetailBuilder<R>	predicate(Predicate<? super R> predicate)	Sets the predicate of this operand.
RelRule.OperandDetailBuilder<R>	trait(RelTrait trait)	Sets a trait of this operand.
RelRule.Done	unorderedInputs(RelRule.OperandTransform... transforms)	Indicates that this operand has several inputs, unordered.
