    • save

      @NonNull <S extends E> @NonNull io.reactivex.Single<S> save(@NonNull S entity)
      Saves the given valid entity, returning a possibly new entity representing the saved state.
      Type Parameters:
      S - The generic type
      Parameters:
      entity - The entity to save. Must not be null.
      Returns:
      The saved entity will never be null.

    • saveAll

      @NonNull <S extends E> @NonNull io.reactivex.Flowable<S> saveAll(@NonNull @NonNull Iterable<S> entities)
      Saves all given entities, possibly returning new instances representing the saved state.
      Type Parameters:
      S - The generic type
      Parameters:
      entities - The entities to save. Must not be null.
      Returns:
      The saved entities objects. will never be null.

    • findById

      @NonNull @NonNull io.reactivex.Maybe<E> findById(@NonNull ID id)
      Retrieves an entity by its id.
      Parameters:
      id - The ID of the entity to retrieve. Must not be null.
      Returns:
      the entity with the given id or Optional#empty() if none found

    • update

      @NonNull <S extends E> @NonNull io.reactivex.Single<S> update(@NonNull S entity)
      This method issues an explicit update for the given entity. The method differs from save(Object) in that an update will be generated regardless if the entity has been saved previously or not. If the entity has no assigned ID then an exception will be thrown.
      Type Parameters:
      S - The generic type
      Parameters:
      entity - The entity to update. Must not be null.
      Returns:
      The updated entity will never be null.

    • updateAll

      @NonNull <S extends E> @NonNull io.reactivex.Flowable<S> updateAll(@NonNull @NonNull Iterable<S> entities)
      This method issues an explicit update for the given entities. The method differs from saveAll(Iterable) in that an update will be generated regardless if the entity has been saved previously or not. If the entity has no assigned ID then an exception will be thrown.
      Type Parameters:
      S - The generic type
      Parameters:
      entities - The entities to update. Must not be null.
      Returns:
      The updated entities will never be null.

    • existsById
