C++ constructor.

Destructor.

Cancel current request, if any, and all other outstanding requests. Client will be notified through MMPXPlaylistEngineObserver's HandlePlaylistL if there is a current request being cancelled.

Cleanup after processing the current task.

2nd phase contructor.

From CActive. Implements cancellation of an outstanding request.

From MMPXTaskQueueObserver. Execute a task.

Execute a task.

Externalize a playlist (async). Before issuing this request, client must use CMPXPlaylistPluginHandler to query available plugins and select an appropriate plugin through CMPXPlaylistPluginHandler. A client can issue another request without having to wait for the completion of a request. When a request is complete, client is notified through MMPXPlaylistEngineObserver's HandlePlaylistL method.

NOTE: 1) If the client does not select a plugin prior to issuing this request, this request may or may not fail depending on whether the client has loaded a plugin through previous operation, e.g. InternalizePlaylistL. When a plugin hasn't been selected, processing of the request will result in KErrNotFound error. 2) If the client has successfully selected a playlist plugin prior to issuing this request but the selected playlist plugin has since been uninstalled when this request is ready for processing, KErrNotSupported error will be returned through HandlePlaylistL.

KErrArgument is returned if client fails to comply with any of the above.

Each media item in the playlist must to contain the following attributes:

KMPXMediaGeneralType: This contains the value of EMPXItem KMPXMediaGeneralCategory: This contains the value of EMPXSong

Client is recommended to call CMPXPlaylistPlugin::RequiredAttributes before making a request to export the playlist and provide the rest of attributes required for each media item in the playlist. If client is unable to provide all of those attributes, client MUST at least provide the URI of the media item.

NOTE: It's recommended that client deletes this playlist as soon as this method returns to save memory consumption as playlistengine will have made a copy of the playlist and stored it in the task queue.

Generate to character sets based on locale.

Handles a leave occurring in the request completion event handler ExecuteTaskL.

Handles a leave occurring in the request completion event handler ExecuteTaskL.

From MMPXPlaylistPluginObserver. Callback from a plugin for an InternalizePlaylistL request, in the task queue, which is currently being processed.

From MMPXPlaylistPluginObserver. Callback from a plugin for an ExternalizePlaylistL request, in the task queue, which is currently being processed.

Handle a task error.

Internalize a playlist (async). Client is not required to select an appropriate plugin as one that is capable of handling the given media from its URI is automatically selected. Client can issue another request without having to wait for the completion of a request. When a request is complete, client is notified through MMPXPlaylistEngineObserver's HandlePlaylistL method. When an appropriate playlist plugin cannot be found to handle this request, KErrNotSupported is returned (through MMPXPlaylistEngineObserver's HandlePlaylistL).

Internalize a playlist (async). Client is not required to select an appropriate plugin as one which is capable of handling the given file is selected automatically. Client can issue another request without having to wait for the completion of a request. When a request is complete, the client is notified through MMPXPlaylistEngineObserver's HandlePlaylistL method. When an appropriate playlist plugin cannot be found to handle this request, KErrNotSupported error is returned.

Determine whether the given character set is specified as top character set.

Determines whether the given media is a playlist from available playlist plugins currently in the system. The existence of the file is not part of this validation process.

An unsupported playlist file is tested as EFalse. But after the appropriate playlist plugin has been installed, the client can retest it and ETrue will be returned.

Two-phased constructor.

returns a handle to playlist plugin handler which a client can use to select an appropriate plugin.

Lifetime for this playlist plugin handler is the same as the playlist engine.

reads the character set for the specified resource.

From CActive. Handles an active object's request completion event.

Select character set(s) for the specified language.
