This class implements a factory mechanism for the objects created to wrap Addresses. It requires that the class passed in implement a constructor taking with the following signature:

public <Type>(sun.jvm.hotspot.Address)

It is used to write shorter code when wrapping Addresses since null checks are no longer necessary. In addition, it is a central location where a canonicalizing map could be implemented if one were desired (though the current system is designed to not require one.)
