public interface CommandIdGenerator
```
The CommandIdGenerator is responsible for generating cache entry ids and data ids, and invalidating data ids for command objects.
One IdGenerator instance will exist for each cacheable command object identified in WebSphere. When implementing this interface, be aware that multiple threads may be using the same IdGenerator concurrently.
