Class TimeTrace

java.lang.Object
  org.nuiton.util.TimeTrace

public class TimeTrace
extends Object

Cette classe permet de facilement trace le temps d'execution entre deux points usage

 TimeTrace timeTrace = new TimeTrace(5000, 1000);


 long start = timeTrace.getTime();
 ...
 // do some work
 ...
 timeTrace.add(start, "do some work");


 System.out.println ("time: " + timeTrace.getCallCount());
