The CBaseList method implements an abtract list. The CGenericList class template, which derives from CBaseList, provides type checking and a simpler API than the CBaseList class.
The CBaseList class is modeled after the CObList class in the Microsoft® Foundation Classes (MFC) library. Positions within the list are represented by a POSITION structure. The caller should not access the internal members of the POSITION structure; treat it as a pointer to a list node. The position of an object in the list remains valid until the object is deleted.
The list does not require any support by the objects it contains. It performs no storage management or copying on the objects. Objects can be in multiple lists.
Roughly half of the methods in this class act on single objects. These methods have the suffix -I in the method name. The other methods act on entire lists. For example, the CBaseList::AddAfter method appends a list to another list. Single-object operations return POSITION values, or NULL on failure. List operations return TRUE if successful or FALSE otherwise.
Header: Declared in Wxlist.h; include Streams.h.
Library: Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
