Detailed Description

Class factory that any plug-in defines for creating class instances: IPluginFactory.

• [plug imp]

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

virtual tresult getFactoryInfo ( PFactoryInfo *  info )

pure virtual

Fill a PFactoryInfo structure with information about the plug-in vendor.

virtual int32 countClasses ( )
