Method Detail
-
getAudioDevice
protected AudioDevice getAudioDevice() throws JavaLayerException
Retrieves theAudioDevice
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 classjava.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 classjava.applet.Applet
-
stop
public void stop()
Stops this applet. If audio is currently playing, it is stopped.- Overrides:
stop
in classjava.applet.Applet
-
destroy
public void destroy()
- Overrides:
destroy
in classjava.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 interfacejava.lang.Runnable
