static IMPORT_C CRemConAbsVolController *NewL(CRemConInterfaceSelector &aInterfaceSelector, MRemConAbsVolControllerObserver &aObserver);

Description

Factory function.

Parameters

CRemConInterfaceSelector &aInterfaceSelector The interface selector. The client must have created one of these first. MRemConAbsVolControllerObserver &aObserver The observer of this interface.

Return value

CRemConAbsVolController * A new CRemConAbsVolController, owned by the interface selector.

IMPORT_C ~CRemConAbsVolController();

Description

Destructor.

IMPORT_C void GetAbsoluteVolume(TRequestStatus &aStatus, TUint &aNumRemotes);

Description

Sends a 'get absolute volume' command. The absolute volume will be returned in response(s) via the observer interface.

Parameters

TRequestStatus &aStatus Used by RemCon to indicate completion of the send request. TUint &aNumRemotes The number of remotes to which the command was sent.

IMPORT_C void SetAbsoluteVolume(TRequestStatus &aStatus, TUint aAbsVol, TUint aMaxVol, TUint &aNumRemotes);

Description

Sends a 'set absolute volume' command. The volume is set to aAbsVol, on a range of zero to aMaxVol. Any responses will be returned via the observer interface.

Parameters

TRequestStatus &aStatus Used by RemCon to indicate completion of the send request. TUint aAbsVol The relative volume. TUint aMaxVol The maximum against which aAbsVol is relative. TUint &aNumRemotes The number of remotes to which the command was sent.

private: virtual TAny *GetInterfaceIf(TUid aUid);

Description

Called by the interface selector to get a pointer to an object which implements the interface API with UID aUid. This is a mechanism for allowing future change to the interface API without breaking BC in existing (non-updated) interfaces.

Parameters

TUid aUid

Return value

TAny *

private: virtual void MrcibNewMessage(TUint aOperationId, const TDesC8 &aData);

Description

Called when a message comes in for this interface.

Parameters

TUint aOperationId The interface-specific operation id. const TDesC8 &aData Any operation-specific data.
