Description

TConnectionDef is an abstract class. When registering a new connection type for use in the universal connector, a descendent of this class must be made and registered using RegisterConnection. A descendent class should override at least the TConnectionDef.TypeName and TConnectionDef.ConnectionClass methods to return the specific name and connection class to use.
