Detailed Description

Class factory that any Plug-in defines for creating class instances.

From the host's point of view a Plug-in module is a factory which can create a certain kind of object(s). The interface IPluginFactory provides methods to get information about the classes exported by the Plug-in and a mechanism to create instances of these classes (that usually define the IPluginBase interface).

An implementation is provided in public.sdk/source/common/pluginfactory.cpp
