31 * This is the generic interface that handles different repository flavours, currently for
32 * ManagedRepository, RemoteRepository and RepositoryGroup
34 * Lifecycle/states of a repository:
36 * <li>Instance created: This state is reached by the newInstance-methods. The instance is created, filled with the
37 * corresponding attribute data and references are updated. References are object references to other repositories, if they exist.
38 * The instance is not registered on the registry (stored) and configuration is not updated.</li>
39 * <li>Instance registered: Instances added/updated by the put()-methods are created and registered on the registry.
40 * If all goes well, the configuration is updated.</li>
41 * <li>Instance initialized: </li>
