Annotation Type Repository

@Retention(value=RUNTIME)
 @Target(value=TYPE)
 @Documented
public @interface Repository

Identifies a Repository. Repositories simulate a collection of aggregates to which aggregate instances can be added and removed. They usually also expose API to select a subset of aggregates matching certain criteria. Access to projections of an aggregate might be provided as well but also via a dedicated separate abstraction.

Implementations use a dedicated persistence mechanism appropriate to the data structure and query requirements at hand. However, they should make sure that no persistence mechanism specific APIs leak into client code.
