Dynamic Playlist Management Web Methods

PagedList<DynamicPlaylist> GetDynamicPlaylists(string marker, int pageSize)

Retrieves the next page of the Dynamic Playlist list, sorted alphabetically by Name string. AudioDynamicPlaylist and/or ImageVideoDynamicPlaylist instances are sorted alphabetically by Name string. The returned list will contain no more items than the defined page size.

Required Permissions

Dynamic Playlist: View Dynamic Playlists

Parameters

  • marker string: The Name string of the last instance on the previous page. If the value is Null, then the method will retrieve the first page.

    • The name of the Dynamic Playlist is more than 50 characters.

    • The content files do not match the type of Dynamic Playlist instance that has been passed to the method (e.g. an AudioDynamicPlaylist contains image or video files, or vice versa).

bool UpdateDynamicPlaylist(DynamicPlaylist entity)

Updates the Name string and Contents List<DynamicPlaylistContent> properties of the specified ImageVideoDynamicPlaylist or AudioDynamicPlaylist instance and its related MRSS file. This method returns True upon success and False upon failure.

Required Permissions

Dynamic Playlist: Update Dynamic Playlist – Content: Assign Content, Unassign Content

Parameters

  • entity DynamicPlaylist: An ImageVideoDynamicPlaylist or AudioDynamicPlaylist object instance with initialized Name string and Contents List<DynamicPlaylistContent> properties. All other properties will be ignored. If the instance is set to Null, then the method will immediately return Null without error. A descriptive error will be returned to the client if any of the following conditions occur:

    • The passed string is more than 50 characters.

    • The passed string does not match a preexisting Dynamic Playlist.

    • The DisplayDuration int of a DynamicPlaylistContent entity-relation is set to less than 1 second. This only applies to entity-relations representing image files.

bool RenameDynamicPlaylist(int dynamicPlaylistId, string newName)

Updates the Name string of the specified ImageVideoDynamicPlaylist or AudioDynamicPlaylist instance. This method returns True upon success and False upon failure.

Required Permissions

Dynamic Playlist: Update Dynamic Playlist, Rename Dynamic Playlist

Parameters

  • dynamicPlaylistId int: The identifier and primary key of the instance. If an instance with the specified identifier does not exist, the method will return False without error.

  • newName string: The new name for the specified instance. A descriptive error will be returned to the client if the passed string is more than 50 characters.

bool DeleteDynamicPlaylists(int[] dynamicPlaylistIds)

Deletes the specified ImageVideoDynamicPlaylist and/or AudioDynamicPlaylist instances from both the database and persistent storage. Related MRSS files are also removed. This method returns True upon success and False upon failure.

Required Permissions

Dynamic Playlist: Delete Dynamic Playlist

Parameters

  • dynamicPlaylistIds int[]: An array of Id int values for the instances to be deleted. The number of items that can be deleted is limited to 100 by the server. Requesting more than the maximum allowed number of objects will cause an error. An error will also be returned if one or more specified Id int value refers to a non-existent ImageVideoDynamicPlaylist or AudioDynamicPlaylist instance. Passing an empty array or Dynamic Playlist identifiers that don’t exist will lead to an immediate empty response without an error.
