Member Enumeration Documentation

anonymous enum

anonymous enum

An enumeration for keeping track of the concrete subclass of VPValue that are actually instantiated.

Values of this enumeration are kept in the SubclassID field of the VPValue objects. They are used for concrete type identification.
