/**
* A visitor of files. This class implements part of the "visitor" design pattern for
* Path objects. The function in the visitor is called depending on the
* run-time type of the object being visited. Calling visitor methods returns some
* value, the type of which depends on the semantics of the visitor in question. In
* general, you will create a visitor object, and then pass it to the
* Path.accept() method of the object in question.
