Region

All Known Implementing Classes:

```
public interface DomainDataRegion
extends Region
```
A second-level cache region that holds cacheable domain data:
- the destructured state of entity instances and collections, and
- mappings from natural id to primary key.
This type of data has:
- key and value wrapping that should to be applied, and
- defined policies for managing concurrent data access, possibly including some form of locking.
These behaviors are defined by an instance of EntityDataAccess, CollectionDataAccess, or NaturalIdDataAccess).
