    Modifier and Type
    Method
    Description
    double
    getFrameRate()
    Get the current number of frames per second (fps).
    long
    getResolution()
    Get the resolution used by this timer.
    long
    getTime()
    Get elapsed time since this timer was created or reset, in the resolution specified by the implementation (usually in nanoseconds).
    double
    getTimeInSeconds()
    Get elapsed time in seconds since this timer was created or reset.
    double
    getTimePerFrame()
    Get the time elapsed between the latest two frames, in seconds.
    void
    reset()
    Reset this timer, so that getTime() and getTimeInSeconds() reflects the time spend from this call.
    void
    update()
    Update should be called once per frame to correctly update "time per frame" and "frame rate (fps)"
