Detailed Description

The main class for processing parsed elements.

DDLElementRegistry.h - description

begin : Wed Oct 24 2001 email : case@.nosp@m.ucdh.nosp@m.ep.uc.nosp@m.davi.nosp@m.s.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.

DDXMLElement * DDLElementRegistry::getElement

(

const std::string &

name

)

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.
