Method Detail

getAudioDevice

protected AudioDevice getAudioDevice()
                              throws JavaLayerException

Retrieves the AudioDevice instance that will be used to sound the audio data.

Returns:

an audio device instance that will be used to sound the audio stream.

Throws:

JavaLayerException

getAudioStream

protected java.io.InputStream getAudioStream()

Retrieves the InputStream that provides the MPEG audio stream data.

Returns:

an InputStream from which the MPEG audio data is read, or null if an error occurs.

getAudioFileName

protected java.lang.String getAudioFileName()

getAudioURL

protected java.net.URL getAudioURL()

setFileName

public void setFileName(java.lang.String name)

Sets the URL of the audio stream to play.

getFileName

public java.lang.String getFileName()

stopPlayer

protected void stopPlayer()
                   throws JavaLayerException

Stops the audio player. If the player is already stopped this method is a no-op.

Throws:

JavaLayerException

play

protected void play(java.io.InputStream in,
        AudioDevice dev)
             throws JavaLayerException

Decompresses audio data from an InputStream and plays it back through an AudioDevice. The playback is run on a newly created thread.

Parameters:

in - The InputStream that provides the MPEG audio data.

dev - The AudioDevice to use to sound the decompressed data.

Throws:

JavaLayerException - if there was a problem decoding or playing the audio data.

createPlayerThread

protected java.lang.Thread createPlayerThread()

Creates a new thread used to run the audio player.

Returns:

A new Thread that, once started, runs the audio player.

init

public void init()

Initializes this applet.

Overrides:

init in class java.applet.Applet

start

public void start()

Starts this applet. An input stream and audio device are created and passed to the play() method.

Overrides:

start in class java.applet.Applet

stop

public void stop()

Stops this applet. If audio is currently playing, it is stopped.

Overrides:

stop in class java.applet.Applet

destroy

public void destroy()

Overrides:

destroy in class java.applet.Applet

run

public void run()

The run method for the audio player thread. Simply calls play() on the player to play the entire stream.

Specified by:

run in interface java.lang.Runnable
