IsisCacheBackendOnGuava (ISIS-Fish 4.4.4.3 API)

java.lang.Object
- fr.ifremer.isisfish.util.cache.IsisCacheBackendOnGuava

All Implemented Interfaces:

IsisCacheBackend
```
public class IsisCacheBackendOnGuava
extends Object
implements IsisCacheBackend
```
Cache qui reserve de la place pour l'equivalent de N pas de temps dans le cache. Une premiere instanciation du cache est faite. Puis apres le premier pas de temps on regarde la taille des objets ayant ete ajoutes au cache pour recalculer la nouvelle taille pour permettre de stocker N pas de temps.
