JavaInformations (JavaMelody - Core 1.98.0 API)

java.lang.Object
- net.bull.javamelody.internal.model.JavaInformations

All Implemented Interfaces:

Serializable
```
public class JavaInformations
extends Object
implements Serializable
```
Informations systèmes sur le serveur, sans code html de présentation. L'état d'une instance est initialisé à son instanciation et non mutable; il est donc de fait thread-safe. Cet état est celui d'une instance de JVM java, de ses threads et du système à un instant t. Les instances sont sérialisables pour pouvoir être transmises au serveur de collecte.
