Public methods

getChildren

public ListenableFuture<LibraryResult> getChildren (String parentId, 
                int page, 
                int pageSize, 
                MediaLibraryService.LibraryParams params)

Gets the list of children under the parent.

If it's successfully completed, LibraryResult.getMediaItems() will return the list of children.

Parameters
`parentId`	`String`: non-empty parent id for getting the children
`page`	`int`: page number to get the result. Starts from `0`
`pageSize`	`int`: page size. Should be greater or equal to `1` Value is 1 or greater.
`params`	`MediaLibraryService.LibraryParams`: library params

Returns
`ListenableFuture<LibraryResult>`

See also:

LibraryResult.getMediaItems()

getItem

public ListenableFuture<LibraryResult> getItem (String mediaId)

Gets the media item with the given media id.

If it's successfully completed, LibraryResult.getMediaItem() will return the media item.

Parameters
`mediaId`	`String`: non-empty media id for specifying the item

Returns
`ListenableFuture<LibraryResult>`

See also:

LibraryResult.getMediaItem()

getLibraryRoot

public ListenableFuture<LibraryResult> getLibraryRoot (MediaLibraryService.LibraryParams params)

Gets the library root.

If it's successfully completed, LibraryResult.getMediaItem() will return the library root.

Parameters
`params`	`MediaLibraryService.LibraryParams`: library params getting root

Returns
`ListenableFuture<LibraryResult>`

See also:

LibraryResult.getMediaItem()

getSearchResult

public ListenableFuture<LibraryResult> getSearchResult (String query, 
                int page, 
                int pageSize, 
                MediaLibraryService.LibraryParams params)

Gets the search result from lhe library service.

If it's successfully completed, LibraryResult.getMediaItems() will return the search result.

Parameters
`query`	`String`: non-empty search query that you've specified with `search(String, LibraryParams)`.
`page`	`int`: page number to get search result. Starts from `0`
`pageSize`	`int`: page size. Should be greater or equal to `1` Value is 1 or greater.
`params`	`MediaLibraryService.LibraryParams`: library params

Returns
`ListenableFuture<LibraryResult>`

See also:

LibraryResult.getMediaItems()

search

public ListenableFuture<LibraryResult> search (String query, 
                MediaLibraryService.LibraryParams params)

Sends a search request to the library service.

Returned LibraryResult will only tell whether the attemp to search was successful. For getting the search result, waits for getSearchResult(String, int, int, LibraryParams) the search result and calls getSearchResult(String, int, int, LibraryParams)} for getting the result.

Parameters
`query`	`String`: non-empty search query
`params`	`MediaLibraryService.LibraryParams`: library params

Returns
`ListenableFuture<LibraryResult>`

See also:

public ListenableFuture<LibraryResult> subscribe (String parentId, 
                MediaLibraryService.LibraryParams params)

Subscribes to a parent id for the change in its children. When there's a change, MediaBrowser.BrowserCallback.onChildrenChanged(MediaBrowser, String, int, LibraryParams) will be called with the library params. You should call getChildren(String, int, int, LibraryParams) to get the items under the parent.

Parameters
`parentId`	`String`: non-empty parent id
`params`	`MediaLibraryService.LibraryParams`: library params

Returns
`ListenableFuture<LibraryResult>`

unsubscribe

public ListenableFuture<LibraryResult> unsubscribe (String parentId)

Unsubscribes for changes to the children of the parent, which was previously subscribed with subscribe(String, LibraryParams).

This unsubscribes all previous subscription with the parent id, regardless of the library param that was previously sent to the library service.

Parameters
`parentId`	`String`: non-empty parent id

Returns
`ListenableFuture<LibraryResult>`

MediaBrowser
