Method Details
- getFramesPerSecond
  
  public double getFramesPerSecond()
  
  The number of frames per second according to the last measured frame (instantaneous measure).
  
  Returns:
  
  The estimated frame-per-second measure of the last frame.
- getLastFrameTimeInSeconds
  
  public double getLastFrameTimeInSeconds()
  
  The duration in seconds of the last measured frame.
  
  Returns:
  
  The last frame time in seconds.
- getAverageMeasureCount
  
  public int getAverageMeasureCount()
  
  The number of frames times used to compute the average frame-per-second and frame time. This number augments with the measures until a maximum, where it is reset to 0.
  
  Returns:
  
  The number of frames measure.
- getAverageFramesPerSecond
  
  public double getAverageFramesPerSecond()
  
  The average frame-per-second measure.
  
  Returns:
  
  The average number of frames per second.

  getAverageMeasureCount()
- getAverageFrameTimeInSeconds
  
  public double getAverageFrameTimeInSeconds()
  
  The average frame time.
  
  Returns:
  
  The time used by a frame in average.
- resetAverages
  
  public void resetAverages()
- beginFrame
  
  public void beginFrame()
  
  Start a frame measure.
- endFrame
  
  public void endFrame()
  
  End a frame measure.
