IMPORT_C static 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. Only one command per controller session can be outstanding at any one time.

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. Only one command per controller session can be outstanding at any one time.

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.
