- io.github.mmm.entity.id.AbstractId<E,I,Instant>
- - io.github.mmm.entity.id.AbstractInstantId<E,UUID>
  - - io.github.mmm.entity.id.UuidInstantId<E>

Type Parameters:

E - the generic type of the identified entity.

All Implemented Interfaces:

Id<E>
```
public class UuidInstantId<E>
extends AbstractInstantId<E,UUID>
```
Implementation of AbstractInstantId using UUID as primary key. Can be used in two scenarios:
- Your data store uses UUIDs natively as primary key (e.g. apache cassandra supports this). In such case you will always directly use a UUID as the actual primary key.
- You may need to express a link to a transient entity. Then you can temporary assign a UUID to the entity on the client and link it via such ID. On the server-side the actual UuidInstantId will then be replaced with the actual ID while persisting the data.
Since:

1.0.0
