                       DataSpec dataSpec,
                       int type,
                       ParsingLoadable.Parser<? extends T> parser)

Parameters:

dataSource - A DataSource to use when loading the data.

dataSpec - The DataSpec from which the object should be loaded.

Method Detail

load

public static <T> T load(DataSource dataSource,
                         ParsingLoadable.Parser<? extends T> parser,
                         android.net.Uri uri,
                         int type)
                  throws java.io.IOException

Loads a single parsable object.

Parameters:

dataSource - The DataSource through which the object should be read.

parser - The ParsingLoadable.Parser to parse the object from the response.

uri - The Uri of the object to read.

type - The type of the data. One of the CDATA_TYPE_* constants.

Returns:

The parsed object

Throws:

java.io.IOException - Thrown if there is an error while loading or parsing.

getResult

@Nullable
public final T getResult()

Returns the loaded object, or null if an object has not been loaded.

bytesLoaded

public long bytesLoaded()

Returns the number of bytes loaded. In the case that the network response was compressed, the value returned is the size of the data after decompression. Must only be called after the load completed, failed, or was canceled.

getUri

public android.net.Uri getUri()

Returns the Uri from which data was read. If redirection occurred, this is the redirected uri. Must only be called after the load completed, failed, or was canceled.

getResponseHeaders

public java.util.Map<java.lang.String,java.util.List<java.lang.String>> getResponseHeaders()

Returns the response headers associated with the load. Must only be called after the load completed, failed, or was canceled.

cancelLoad

public final void cancelLoad()

Description copied from interface: Loader.Loadable

Cancels the load.

Specified by:

                throws java.io.IOException

Description copied from interface: Loader.Loadable

Performs the load, returning on completion or cancellation.

Specified by:

load in interface Loader.Loadable

Throws:
