All Implemented Interfaces:

Poolable<ProcessData>
```
public class ProcessData
extends java.lang.Object
implements Poolable<ProcessData>
```
Stores and gathers data on the currently running (JVM) process and the underlying operating system. Several data collected in this class needs native system support to be obtained.
