    Modifier and Type
    Method
    Description
    long
    count()
     
    void
    delete(E entity)
    Deletes one entity, managed or detached, as Spring Data's delete does: a detached instance is merged first, so the row it stands for is removed.
    void
    deleteAll()
    Deletes every entity of this type, one by one, so cascades and lifecycle callbacks run as they do for delete.
    void
    deleteAll(Iterable<? extends E> entities)
    Deletes each of the given entities, as delete does.
    void
    deleteById(K id)
     
    boolean
    existsById(K id)
     
    List<E>
    findAll()
     
    List<E>
    findAllById(Iterable<K> ids)
    The entities whose ids are given, in the order given; an id with no row is skipped, so the list can be shorter than the input.
    E
    findById(K id)
     
    void
    flush()
    Writes pending changes of the caller's session now, rather than at commit.
    void
    insert(E entity)
     
    E
    save(E entity)
     
    List<E>
    saveAll(Iterable<? extends E> entities)
    Saves each of the given entities, as save does, and answers the managed results in the same order.
