Examples of org.sf.bee.profiler.components.TimeWatcher

org.sf.bee.profiler.components.TimeWatcher
Simple class to measure application performance.
Just call "start" and "stop" to obtain your action's elapsed time.
To start the watch, call {@link #start()}. At this point you can:
- {@link #split()} the watch to get the time whilst the watch continues in thebackground. {@link #unsplit()} will remove the effect of the split. At this point,these three options are available again.
- {@link #suspend()} the watch to pause it. {@link #resume()} allows the watchto continue. Any time between the suspend and resume will not be counted in the total. At this point, these three options are available again.
- {@link #stop()} the watch to complete the timing session.
It is intended that the output methods {@link #toString()} and {@link #getTime()}should only be called after stop, split or suspend, however a suitable result will be returned at other points.

NOTE: The methods protect against inappropriate calls. Thus you cannot now call stop before start, resume before suspend or unsplit before split.

1. split(), suspend(), or stop() cannot be invoked twice
2. unsplit() may only be called if the watch has been split()
3. resume() may only be called if the watch has been suspend()
4. start() cannot be called twice without calling reset()
