PHPParser get_all_class_method_bodies not work

The documentation says that PHP parser has a get_all_class_method_bodies method, but there is no such method. How do I get the body of class methods?

Start by locating the documentation entry for PHPParser and searching the repository for get_all_class_method_bodies and the PHP parser entry point. Compare the documented API with the available implementation, then verify how class method bodies are currently exposed or whether the missing method should be documented or added.
