Class CDaIncremental

class CDaIncremental : public CBase, public MDaIncremental;

Description

CBase-based class for classes that implement data model incremental operations.

Derivation

• MDaIncremental - Abstract interface for classes that implement data model incremental operations
• CBase - Base class for all classes to be instantiated on the heap

• CDaIncremental - CBase-based class for classes that implement data model incremental operations

inline CDaIncremental();

Description

Constructor.

IMPORT_C void SetObserver(MDaIncrementalObserver *aObserver);

Description

Sets the operation observer.

Parameters

MDaIncrementalObserver *aObserver Operation observer

virtual inline void SetActiveIncremental(CDaActiveIncremental *aActiveIncremental);

Description

Sets the active object using this interface.

Parameters

CDaActiveIncremental *aActiveIncremental Incremental active object

inline TInt TerminationState() const;

Description

Gets the operation's terminal state.

Return value

TInt Terminal state identifier

inline void Initialize(TInt aRemainingSteps);

Description

Initialises the object with the number of remaining steps in the operation.

Parameters

TInt aRemainingSteps Number of remaining steps in the operation

virtual IMPORT_C void HandleCancel();

Description

Handles the operation being cancelled.

virtual IMPORT_C void HandleLeave(TInt aError);

Description

Handles leave conditions in operation steps.

Parameters

TInt aError Leave code
