## Detailed Description

The purpose of this class is to provide a way to get the "preferred" or closest matching type for XObject-derived classes.

The idea is to pass a reference to an instance of this class to an XObject instance. It will then call back to the member function that most closely matches its type. This makes it possible to get preferred typing information without doing RTTI or other such type introspections.
