[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The CGenericList class template that implements a type-specific list. For more information, see CBaseList.
To use this template, declare a variable of type CGenericList with a template argument that defines the type of object in the list. For example, the following statement declares a list of CBaseFilter objects:
CGenericList<CBaseFilter> myFilterList("Filters");
For convenience, Wxlist.h defines the following list types:
typedef CGenericList<CBaseObject> CBaseObjectList;
typedef CGenericList<IUnknown> CBaseInterfaceList;
