public long	Returns: Duration of the last update interval in milliseconds. getLastFPSPeriod()
public long	getLastFPSUpdateTime() Returns the time of the last update interval in milliseconds, if this feature is enabled via `setUpdateFPSFrames(int, PrintStream)`.
public float	Returns: Total frames per seconds, `getTotalFPSFrames()` / `getTotalFPSDuration()` getTotalFPS()
public long	Returns: Total duration in milliseconds, `getLastFPSUpdateTime()` - `getFPSStartTime()` getTotalFPSDuration()
public int	Returns: Number of frame rendered since `getFPSStartTime()` up to `getLastFPSUpdateTime()` getTotalFPSFrames()
public int	Returns: update interval in frames getUpdateFPSFrames()
public void	resetFPSCounter() Reset all performance counter (startTime, currentTime, frame number)
public void	setUpdateFPSFrames(int Update interval in frames. At every rendered frames interval the currentTime and fps values are updated. If the frames interval is <= 0, no update will be issued, ie the FPSCounter feature is turned off. You may choose `DEFAULT_FRAMES_PER_INTERVAL`. frames, PrintStream optional print stream where the fps values gets printed if not null at every frames interval out)

setUpdateFPSFrames	back to summary
public void setUpdateFPSFrames(int frames, PrintStream out) Parameters frames:int Update interval in frames. At every rendered frames interval the currentTime and fps values are updated.

You may choose `DEFAULT_FRAMES_PER_INTERVAL`. out:PrintStream optional print stream where the fps values gets printed if not null at every frames interval

public void setUpdateFPSFrames(int frames, PrintStream out)

Parameters

frames:int: Update interval in frames.
