Useful for all kind of profilings, time measurements etc. Field Summary protected  List<long[]> laps      List of all laps. protected  String name      Optional stopwatch name. protected  boolean running      Running flag. protected  long spanTime      Last elapsed time. protected  long startTime      Last start time. protected  long stopTime      Last stop time. protected  long totalTime      Cumulative elapsed time. Constructor Summary public   JStopWatch()      Starts the stopwatch. public   JStopWatch(String name)      Starts the named stopwatch. Method Summary public  long elapsed()      Returns total elapsed time from the JStopWatch.start() in ms. public static  String formatTimeSpan(long millis)      Formats time spans. public  long[] getLapTimes(int index)      Returns lap times for 1-based lap index. public  String getName()      Returns stopwatch name. public  boolean isRunning()      Returns true if stopwatch is running. public  long lap()      Marks a lap and returns its length. protected  long lap(long lap)      public  long restart()      Restarts the stopwatch. public  long span()      Stops the stopwatch and returns total time span for last start-stop sequence. public  long start()      Starts the stopwatch. public  long stop()      Stops the stopwatch if running. public  String toString()      Returns total elapsed time as formated string from the last start. public  long total()      Stops the stopwatch and returns total cumulative time in ms. public  int totalLaps()      Returns the total number of laps up to this moment. Field Detail laps protected List<long[]> laps(Code) List of all laps. Contains long arrays in following format: lap time - current lap time, lap span time - elapsed time from start, lap millis - lap milliseconds. name protected String name(Code) Optional stopwatch name. running protected boolean running(Code) Running flag. spanTime protected long spanTime(Code) Last elapsed time. startTime protected long startTime(Code) Last start time. stopTime protected long stopTime(Code) Last stop time. totalTime protected long totalTime(Code) Cumulative elapsed time. Constructor Detail JStopWatch public JStopWatch()(Code) Starts the stopwatch. JStopWatch public JStopWatch(String name)(Code) Starts the named stopwatch. Method Detail elapsed public long elapsed()(Code) Returns total elapsed time from the JStopWatch.start() in ms. formatTimeSpan public static String formatTimeSpan(long millis)(Code) Formats time spans. getLapTimes public long[] getLapTimes(int index)(Code) Returns lap times for 1-based lap index. Returns null if laps are not used or if index is invalid. getName public String getName()(Code) Returns stopwatch name. isRunning public boolean isRunning()(Code) Returns true if stopwatch is running. lap public long lap()(Code) Marks a lap and returns its length. May be called only while stop watch is running. lap protected long lap(long lap)(Code) restart public long restart()(Code) Restarts the stopwatch. span public long span()(Code) Stops the stopwatch and returns total time span for last start-stop sequence. start public long start()(Code) Starts the stopwatch. JStopWatch.stop() must be called prior to restart. Returns starting time in milliseconds. stop public long stop()(Code) Stops the stopwatch if running. Returns span time. If laps are used, marks the last lap. toString public String toString()(Code) Returns total elapsed time as formated string from the last start. total public long total()(Code) Stops the stopwatch and returns total cumulative time in ms. totalLaps public int totalLaps()(Code) Returns the total number of laps up to this moment.
