Examples of com.google.common.base.Stopwatch.elapsed()

com.google.common.base.Stopwatch.elapsed()
Returns the current elapsed time shown on this stopwatch, expressed in the desired time unit, with any fraction rounded down.
Note that the overhead of measurement can be more than a microsecond, so it is generally not useful to specify {@link TimeUnit#NANOSECONDS}precision here. @since 14.0 (since 10.0 as {@code elapsedTime()})
