NumericVersionGenerator (Red Hat Data Grid 7.3.9 API)

java.lang.Object
- org.infinispan.container.versioning.NumericVersionGenerator

All Implemented Interfaces:

VersionGenerator
```
public class NumericVersionGenerator
extends Object
implements VersionGenerator
```
Generates unique numeric versions for both local and clustered environments. When used on clustered caches, node information is used to guarantee versions are unique cluster-wide. If the cache is configured to be local, the version generated is based around an atomic counter. On the contrary, if the cache is clustered, the generated version is composed of: [view id (2 bytes)][rank (2 bytes)][version counter (4 bytes)], where rank refers to the position of this node within the view.
