CRemConMediaBrowseTargetBase Class Reference

class CRemConMediaBrowseTargetBase : public CRemConInterfaceBase

This interface enables the client to present a heirarchical view of the local media library for browsing by a remote entity.

The view is a virtual filesystem and does not need to correspond directly to any structure on local storage. It could for example map onto a database of media content.

Each item in the media library is identified by a UID. At a minimum this must uniquely identify an element within a folder. For clients that support it the UID can be persistant accross the entire virtual filesystem. In this case a media library state cookie is used to ensure that that state is consistent between the client and the remote device.

This interface does not have NewL()/NewLC, so the client should use the object CRemConDatabaseAwareMediaBrowseTarget or CRemConDatabaseUnawareMediaBrowseTarget to use its exported functions.

This class is only to be used by classes currently derived from it.
