dataSource - The source from which the data should be loaded.

dataSpec - Defines the data to be loaded.

type - See Chunk.type.

trackFormat - See Chunk.trackFormat.

trackSelectionReason - See Chunk.trackSelectionReason.

trackSelectionData - See Chunk.trackSelectionData.

data - An optional recycled array that can be used as a holder for the data.

Method Detail

getDataHolder

public byte[] getDataHolder()

Returns the array in which the data is held.

This method should be used for recycling the holder only, and not for reading the data.

Returns:

The array in which the data is held.

bytesLoaded

public long bytesLoaded()

Description copied from class: Chunk

Returns the number of bytes that have been loaded.

Specified by:

bytesLoaded in class Chunk

cancelLoad

public final void cancelLoad()

Description copied from interface: Loader.Loadable

Cancels the load.

isLoadCanceled

public final boolean isLoadCanceled()

Description copied from interface: Loader.Loadable

Returns whether the load has been canceled.

load

public final void load()
                throws java.io.IOException,
                       java.lang.InterruptedException

Description copied from interface: Loader.Loadable

Performs the load, returning on completion or cancellation.

Throws:

java.io.IOException - If the input could not be loaded.

java.lang.InterruptedException - If the thread was interrupted.

consume

protected abstract void consume(byte[] data,
                                int limit)
                         throws java.io.IOException

Called by load(). Implementations should override this method to consume the loaded data.

Parameters:

data - An array containing the data.

limit - The limit of the data.

Throws:

java.io.IOException - If an error occurs consuming the loaded data.
