Detailed Description

The main class for processing parsed elements.

DDLElementRegistry.h - description ------------------- begin : Wed Oct 24 2001 email : case@ucdhep.ucdavis.edu

This class is designed to serve as a registry of all DDL XML elements. It inherits from DDXMLElementRegistry.

This class is responsible for constructing and destructing any necessary DDL element.

THE most important part. Getting the pointer to a given element type.

If this is called with a DDXMLElementRegistry pointer, it will simply return a pointer if already registered or NULL, no instantiating.

Reimplemented from DDXMLElementRegistry.
