MrcdanpboGetFolderListing(TUint, TUint)

void	MrcdanpboGetFolderListing	(	TUint	aStartItem,
			TUint	aEndItem
		)	[pure virtual]

Requests a listing of the items present in the Now Playing folder. If the media player does not natively support a Now Plyaing folder the client shall return a listing of one item which is the currently playing media element.

No metadata is requested, that can be retrieved separately on a per item basis. Trying this out for now as it fits in with the existing metadata attribute collection, and means that we would also separate out the listing from the metadata. This means that we can retrieve a NowPlaying list and then request the metadata from the observer.

The result shall be returned via a call to MRemConDatabaseAwareNowPlayingBrowse::MrcdanpbFolderListing()

Parameters

TUint aStartItem	The offset into the folder listing of the first item to retrieve. If there is no media available at this offset the error KErrMediaBrowseInvalidOffset shall be returned via the result call to MrcdanpbFolderListing().
TUint aEndItem	The offset into the folder listing of the final item to retrieve. If this is beyond the end of the folder listing then the items from the aStartItem offset to the end of the listing shall be returned via the result call to MrcdanpbFolderListing().

MrcdanpboGetItem(const TRemConItemUid &, TMediaAttributeIter &, TUint16)

TInt	MrcdanpboGetItem	(	const TRemConItemUid &	aItemId,
			TMediaAttributeIter &	aIter,
			TUint16	aMediaLibraryStateCookie
		)	[pure virtual]

Requests a set of metadata corresponding to a specific media element item.

The client must return the metadata for the requested item via using MRemConDatabaseAwareNowPlayingBrowse::MrcdanpbMediaElementItemResult() if it returns KErrNone, if it is unable to to process this call then it can return error but not call the response function MRemConDatabaseAwareNowPlayingBrowse::MrcdanpbMediaElementItemResult() .

Parameters

const TRemConItemUid & aItemId	The UID for the requested media element item.
TMediaAttributeIter & aIter	An iterator for TMediaAttributeIds containing a list of TMediaAttributeIds requested by the controller.
TUint16 aMediaLibraryStateCookie	The cookie which the remote device believes refers to the current state of the media library. If this does not match the current state according to the client then the client should call MrcdanpbMediaElementItemResult() with the error KErrInvalidMediaLibraryStateCookie.
