Class anonymous_namespace{RelAlgDagBuilder.cpp}::anonymous_namespace{RelAlgDagBuilder.cpp}::RexInputReplacementVisitorΒΆ
- class
The RexInputReplacement visitor visits each node in a given relational algebra expression and replaces the inputs to that expression with inputs from a different node in the RA tree. Used for coalescing nodes with complex expressions.
