public class InMemoryRepository<T extends Entity>
extends AbstractDomianCoreRepository<T>
implements VolatileRepository<T>

Volatile repository for concurrent environments.

This repository is suitable for all applications with no need for persistent objects.

This repository is backed by a ConcurrentHashMap. Only the Map keys are used, not the values.
