Constructor Detail

PushBufferDataSourceAdapter

public PushBufferDataSourceAdapter(javax.media.protocol.PullBufferDataSource dataSource)

Initializes a new PushBufferDataSourceAdapter which is to implement PushBufferDataSource capabilities for a specific PullBufferDataSource.

Parameters:

dataSource - the PullBufferDataSource the new instance is to implement PushBufferDataSource capabilities for

Method Detail

disconnect

public void disconnect()

Implements DataSource.disconnect(). Disposes of the PushBufferStreamAdapters which wrap the PullBufferStreams of the PullBufferDataSource wrapped by this instance.

Specified by:

disconnect in interface javax.media.protocol.CaptureDevice

Overrides:

disconnect in class PushBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>

getStreams

public javax.media.protocol.PushBufferStream[] getStreams()

Implements PushBufferDataSource.getStreams(). Gets the PushBufferStreams through which this PushBufferDataSource gives access to its media data.

Specified by:

getStreams in class PushBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>

Returns:

an array of PushBufferStreams through which this PushBufferDataSource gives access to its media data

start

public void start()
           throws IOException

Implements DataSource.start(). Starts the wrapped PullBufferDataSource and the pushing from the PushBufferStreamAdapters which wrap the PullBufferStreams of the PullBufferDataSource wrapped by this instance.

Specified by:

start in interface javax.media.protocol.CaptureDevice

Overrides:

start in class PushBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>

Throws:

IOException - if anything wrong happens while starting the wrapped PullBufferDataSource or the pushing from the PushBufferStreamAdapters which wrap the PullBufferStreams of the PullBufferDataSource wrapped by this instance

stop

public void stop()
          throws IOException

Implements DataSource.start(). Stops the wrapped PullBufferDataSource and the pushing from the PushBufferStreamAdapters which wrap the PullBufferStreams of the PullBufferDataSource wrapped by this instance.

Specified by:

stop in interface javax.media.protocol.CaptureDevice

Overrides:

stop in class PushBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>

Throws:

IOException - if anything wrong happens while stopping the wrapped PullBufferDataSource or the pushing from the PushBufferStreamAdapters which wrap the PullBufferStreams of the PullBufferDataSource wrapped by this instance
