Interface Repository<AGGREGATE extends AggregateRoot<KEY>,KEY>

Type Parameters:

AGGREGATE - the type of the aggregate root class.

KEY - the type of the aggregate root class.

All Known Subinterfaces:

GenericRepository<AGGREGATE,KEY>

@DomainRepository
public interface Repository<AGGREGATE extends AggregateRoot<KEY>,KEY>

This interface has to be extended in order to create a Domain Repository interface.

To be a valid repository interface, Type must respect the followings :

• be an interface
• extends Repository

The following is a valid Domain repository interface.

  public interface ProductRepository extends Repository<Product,String> {
     // nothing needed, but you can add methods with specifics
     // then implements them
  }
 

Then this interface has to be implemented by the actual repository implementation . See BaseRepository for details.
