Class NullAudioBuffer

java.lang.Object
  jmri.implementation.AbstractNamedBean
      jmri.implementation.AbstractAudio
          jmri.jmrit.audio.AbstractAudioBuffer
              jmri.jmrit.audio.NullAudioBuffer

All Implemented Interfaces:: Serializable, Audio, AudioBuffer, NamedBean

public class NullAudioBuffer
extends AbstractAudioBuffer
extends AbstractAudioBuffer

Null implementation of the Audio Buffer sub-class.

For now, no system-specific implementations are forseen - this will remain internal-only
