Fields
Modifier and Type	Field	Description
`protected ConcurrentLinkedDeque<Trace.StatAndStack>`	`allStatAndStack`
`protected static ThreadLocal<Trace.StatAndStack>`	`callStacks`	array : [nest method call, start time, start time with child] On ne melange pas les stack entre les threads, sinon les resultats ne veulent plus rien dire car toutes les methodes des threads sont melangees
`protected Map<Method,StatisticMethod>`	`commonStatistics`	statistic on method call
`protected boolean`	`distinctThreadCall`
`protected Trace.StatAndStack`	`monoStatAndStack`
`protected boolean`	`multithread`

Constructor Summary

Constructors
Constructor	Description
`Trace()`	default usable in multi-thread context, all calls in all threads are stored in same place (no thread distinction)
`Trace(boolean multithread, boolean distinctThreadCall)`	indique que l'on utilise Trace seulement avec un thread, cela evite d'utiliser en interne un ThreadLocal

  - Trace
```
public Trace()
```
    default usable in multi-thread context, all calls in all threads are stored in same place (no thread distinction)
  - Trace
```
public Trace(boolean multithread,
             boolean distinctThreadCall)
```
    indique que l'on utilise Trace seulement avec un thread, cela evite d'utiliser en interne un ThreadLocal
    
    Parameters:
    
    multithread - si vrai indique que cette instance est utilise dans un context multithread. Dans ce cas il est possible d'indique la politique de collect des appels via le parametre distinctThreadCall
    
    distinctThreadCall - si vrai indique que les appels des differents thread ne doivent pas etre melange. Si deux thread appel la meme methode cette methode se trouvera dans des statistiques differentes pour chacun des threads
