Examples of org.jamesii.core.util.StopWatch.start()

org.jamesii.core.util.StopWatch.start()
Calling this method corresponds with pressing the start button of this stopwatch. If the stopwatch is already running nothing happens and this method returns false. If the stopwatch is not running, then it is started and true is returned.
You may restart the stopwatch again and again. As long as you don't reset the stop watch, the totally elapsed time increases. @return true, if start
