Constructor Detail

BaseDataSource

protected BaseDataSource(boolean isNetwork)

Deprecated.

Creates base data source. Parameters:isNetwork - Whether the data source loads data through a network.

Method Detail

addTransferListener

public final void addTransferListener([TransferListener](TransferListener.html "interface in com.google.android.exoplayer2.upstream")transferListener)

Deprecated.

Description copied from interface: DataSource

Adds a TransferListener to listen to data transfers. This method is not thread-safe. Specified by:addTransferListener in interface DataSourceParameters:transferListener - A TransferListener.

transferInitializing

protected final void transferInitializing([DataSpec](DataSpec.html "class in com.google.android.exoplayer2.upstream")dataSpec)

Deprecated.

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.html "class in com.google.android.exoplayer2.upstream")dataSpec)

Deprecated.

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)

Deprecated.

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()

Deprecated.

Notifies listeners that a transfer ended.
