isNetwork - Whether the data source loads data through a network.

Method Detail

addTransferListener

public final void addTransferListener(TransferListener transferListener)

Description copied from interface: DataSource

Adds a TransferListener to listen to data transfers. This method is not thread-safe.

Specified by:

addTransferListener in interface DataSource

Parameters:

transferListener - A TransferListener.

transferInitializing

protected final void transferInitializing(DataSpec dataSpec)

Notifies listeners that data transfer for the specified DataSpec is being initialized.

Parameters:

dataSpec - DataSpec describing the data for initializing transfer.

transferStarted

protected final void transferStarted(DataSpec dataSpec)

Notifies listeners that data transfer for the specified DataSpec started.

Parameters:

dataSpec - DataSpec describing the data being transferred.

bytesTransferred

protected final void bytesTransferred(int bytesTransferred)

Notifies listeners that bytes were transferred.

Parameters:

bytesTransferred - The number of bytes transferred since the previous call to this method (or if the first call, since the transfer was started).

transferEnded

protected final void transferEnded()

Notifies listeners that a transfer ended.
