@API(value=EXPERIMENTAL)
public interface Bindable

A planner type that supports rule binding. Both PlannerExpression and ExpressionRef implement Bindable to allow binding to both concrete expressions and groups.

Method Summary

Modifier and Type	Method and Description
Stream<PlannerBindings>	bindTo(ExpressionMatcher<? extends Bindable> binding) Attempt to match the binding to this bindable object.

Method Detail

bindTo

@Nonnull
Stream<PlannerBindings> bindTo(@Nonnull
                                        ExpressionMatcher<? extends Bindable> binding)

Attempt to match the binding to this bindable object.

Parameters:

binding - the binding to match against

Returns:

a map of bindings if the match succeeded, or an empty Optional if it failed
