Constructor Detail

NullAudioSource

public NullAudioSource(java.lang.String systemName)

Constructor for new NullAudioSource with system name.

Parameters:

systemName - AudioSource object system name (e.g. IAS1)

NullAudioSource

public NullAudioSource(java.lang.String systemName,
                       java.lang.String userName)

userName - AudioSource object user name

Method Detail

bindAudioBuffer

boolean bindAudioBuffer(AudioBuffer audioBuffer)

Description copied from class: AbstractAudioSource

Binds this AudioSource with the specified AudioBuffer.

Applies only to sub-types:

• Source

Specified by:

bindAudioBuffer in class AbstractAudioSource

Parameters:

audioBuffer - The AudioBuffer to bind to this AudioSource

Returns:

true if successful

changePosition

protected void changePosition(javax.vecmath.Vector3f pos)

Description copied from class: AbstractAudioSource

Change the current position of this source.

Specified by:

changePosition in class AbstractAudioSource

Parameters:

pos - new position

doPlay

protected void doPlay()

Description copied from class: AbstractAudioSource

Play the clip from the beginning. If looped, start looping.

Specified by:

doPlay in class AbstractAudioSource

doStop

protected void doStop()

Description copied from class: AbstractAudioSource

Stop playing the clip and rewind to the beginning.

Specified by:

doStop in class AbstractAudioSource

doPause

protected void doPause()

Description copied from class: AbstractAudioSource

Stop playing the clip but retain the current position.

Specified by:

doPause in class AbstractAudioSource

doResume

protected void doResume()

Description copied from class: AbstractAudioSource

Play the clip from the current position.

Specified by:

doResume in class AbstractAudioSource

doRewind

protected void doRewind()

Description copied from class: AbstractAudioSource

Rewind clip to the beginning.

Specified by:

doRewind in class AbstractAudioSource

doFadeIn

protected void doFadeIn()

Description copied from class: AbstractAudioSource

Fade in then play this AudioSource.

Specified by:

doFadeIn in class AbstractAudioSource

doFadeOut

protected void doFadeOut()

Description copied from class: AbstractAudioSource

Fade out then stop this AudioSource.

Specified by:

doFadeOut in class AbstractAudioSource

cleanup

protected void cleanup()

Description copied from class: AbstractAudio

Abstract method that concrete classes will implement to perform necessary cleanup routines.

This method is now included in dispose(). The caller can call dispose() to cleanup and deregister an audio object.

Specified by:

cleanup in class AbstractAudio

calculateGain

protected void calculateGain()

Description copied from class: AbstractAudioSource

Calculate the gain of this AudioSource based on distance from listener and fade levels.

Specified by:

calculateGain in class AbstractAudioSource
