Class CDaActiveIncremental

class CDaActiveIncremental : public CActive;

Description

Encapsulates a data model incremental operation in an active object.

Steps in the operation are called from the object's RunL(), and the active object reactivated until all steps are complete.

Derivation

• 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
