    • getRequiredDataHistory

      public long getRequiredDataHistory(PamObservable o, Object arg)
      Required data history depends on what's happening with the mouse. If the mouse is doing nothing and there are no SpectrogramMarkObservers then no data needs to be stored for drawing the spectrogram. If there are mark observers and the mouse is up, then make sure that at least one screen full of data is always in memory (both FFT data and Raw wave data). If the mouse is down, then keep the maximum of either one screen full of from whenever the mouse was pressed - the use may hold it down for a long time !
      Specified by:
      getRequiredDataHistory in interface PamObserver
      Parameters:
      arg - optional argument from PamObservable
      Returns:
      time in milliseconds required by data held in PamObservable
