DataSource

• java.lang.Object
  • javax.media.protocol.DataSource
    • javax.media.protocol.PushBufferDataSource
      • com.sun.media.protocol.BasicPushBufferDataSource

Fields Summary
private PushBufferStream[]	srcStreams
private boolean	stopped
Player	streamplayer

Constructors Summary
public DataSource() srcStreams= new PushBufferStream[ 1];

Methods Summary
public void	connect() Opens a connection to the source described by the URL. Connect initiates communmication with the source. exception IOException thrown if the connect has IO trouble. connected = true;
public void	disconnect() Close the connection to the source described by the URL. Disconnect frees resources used to maintain a connection to the source. If no resources are in use, disconnect is ignored. Implies a stop, if stop hasn't already been called. connected = false;
public java.lang.String	getContentType() return "rtsp";
public java.lang.Object	getControl(java.lang.String controlName) Returns null because no controls are implemented. return null. return null;
public java.lang.Object[]	getControls() Returns an zero length array because no controls are supported. return a zero length Object array. return null;
public javax.media.Player	getPlayer() return streamplayer;
public javax.media.protocol.PushBufferStream[]	getStreams() Obtain the collection of streams that this source manages. The collection of streams is entirely content dependent. The mime-type of this DataSource provides the only indication of what streams can be available on this connection. return collection of streams for this source. if (!connected) return null; return srcStreams;
public boolean	isStarted() return started;
public void	setControl(java.lang.Object control)
public void	setLocator(javax.media.MediaLocator mrl) super.setLocator(mrl);
public void	setPlayer(javax.media.Player player) streamplayer = player;
public void	setSourceStream(javax.media.protocol.PushBufferStream stream) if (srcStreams != null) srcStreams[0] = stream;
public void	start() Initiates data-transfer. Start must be called before data is available. Connect must be called before start. exception IOException thrown if the source has IO trouble at startup time. super.start();
public void	stop() Stops data-transfer. If the source has not already been connected and started, stop does nothing. super.stop();
