Detailed Description

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

  • [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

Member Function Documentation

virtual tresult getFactoryInfo ( PFactoryInfo info)
pure virtual

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

virtual int32 countClasses ( )
pure virtual

Returns the number of exported classes by this factory.

If you are using the CPluginFactory implementation provided by the SDK, it returns the number of classes you registered with CPluginFactory::registerClass.

virtual tresult getClassInfo ( int32  index,
PClassInfo info 
)
pure virtual

Fill a PClassInfo structure with information about the class at the specified index.

virtual tresult createInstance ( FIDString  cid,
FIDString  _iid,
void **  obj 
)
pure virtual

Create a new class instance.
