Member Functions Documentation

AddToNowPlayingResponse(TInt)

IMPORT_C void AddToNowPlayingResponse ( TInt aErr )

Sends the response for the request MrcnptoAddToNowPlaying()

The client must call NowPlayingContentChanged() if the content of the now playing list has been changed after the client successfully adds the item to the now playing list and provides the response with KErrNone through this function.

param aErr The result of add to now playing operation.

  • KErrNone if the operation was successful.

  • KErrInvalidMediaLibraryStateCookie if the client is able to maintain unique UIDs accross the entire virtual filesystem, but the media library state cookie provided does not match the client's state cookie.

  • KErrInvalidUid if the uid of the item provided does not refer to any valid item.

  • KErrNowPlayingUidIsADirectory if the uid of the item provided refers to a directory which can not be handled by this media player.

  • KErrNowPlayingMediaInUse if the item is in use and can not be added to now playing list.

  • KErrNowPlayingListFull if the now playing list if full and no more items can be added.

  • System wide error code otherwise.

NowPlayingContentChanged()

Parameters

TInt aErr

AddToOperationQueue(TInt, const TDesC8 &)

void AddToOperationQueue ( TInt aOperationId,
const TDesC8 & aData
) [private]

Parameters

TInt aOperationId
const TDesC8 & aData

BaseConstructL()

void BaseConstructL ( ) [protected, virtual]

Must be called by concrete types at construction time. Registers the interface with the interface selector.

DoNextMessage()

void DoNextMessage ( ) [private]

GetInterfaceIf(TUid)

TAny * GetInterfaceIf ( TUid aUid ) [private, virtual]

Gets a pointer to a specific interface version.

Parameters

TUid aUid

NowPlayingContentChanged()

IMPORT_C void NowPlayingContentChanged ( )

Called by the client in the case that the now playing content changed.

PlayItemResponse() AddToNowPlayingResponse()

PlayItemResponse(TInt)

IMPORT_C void PlayItemResponse ( TInt aErr )

Provide a response to the play item command. For database aware clients this would have been called via MrcdanptoPlayItem(). For database unaware client this would have been called via MrcdunptoPlayItem()

The client must call NowPlayingContentChanged() if the content of the now playing list has been changed after the client successfully plays the item and provides the response with KErrNone through this function.

NowPlayingContentChanged()
