Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

Implement the Visitor pattern via pseudo double dispatch.

Visitor classes must implement #visit_type methods for each type that may be visited. If the visitor should descend into child objects the #visit_ method should yield to the passed block.

Visitor classes must implement #logger so that error messages can be logged.
