Package org.apache.calcite.rel.rules

Interface FilterProjectTransposeRule.Config

All Superinterfaces:

RelRule.Config

Enclosing class:

FilterProjectTransposeRule

@Immutable
public static interface FilterProjectTransposeRule.Config
extends RelRule.Config

Rule configuration.

If copyFilter is true, creates the same kind of Filter as matched in the rule, otherwise it creates a Filter using the RelBuilder obtained by the relBuilderFactory. Similarly for copyProject.

Defining predicates for the Filter (using filterPredicate) and/or the Project (using projectPredicate allows making the rule more restrictive.
