class CDaActiveIncremental : public CActive;
Encapsulates a data model incremental operation in an active object.
Steps in the operation are called from the object's CDaActiveIncremental::RunL()
, and the active object reactivated until all steps are complete.
CBase
-
Base class for all classes to be instantiated on the heap.
CActive
-
The core class of the active object abstraction.
CDaActiveIncremental
- Encapsulates a data model incremental operation in an active object.
