  • Method Details

    • create

      K create(K1 keyComponent1, T entity)
      Create an entity using a specific first key component, assuming the second component is generated by the database.
      Parameters:
      entity - the domain object so store; the Identity.getId() of the entity will be ignored
      keyComponent - the assigned key component
      Returns:
      the primary key of the stored object

    • findAll

      Collection<T> findAll(K1 keyComponent1, List<net.solarnetwork.domain.SortDescriptor> sorts)
      Find all persisted entities available matching the first key component, optionally sorted in some way.

      The sortDescriptors parameter can be null, in which case the sort order is not defined and implementation specific.

      Parameters:
      keyComponent1 - the first key component to restrict the results to
      sorts - list of sort descriptors to sort the results by
      Returns:
      list of all persisted entities, or empty list if none available

    • findAllForKey

      default Collection<T> findAllForKey(K filter, List<net.solarnetwork.domain.SortDescriptor> sorts)
      Description copied from interface: GenericCompositeKeyFilterableDao
      Find all persisted entities available matching the components of a composite key, optionally sorted in some way.

      Only key components that are assigned are used to filter the result. The sortDescriptors parameter can be null, in which case the sort order is not defined and implementation specific.

      Specified by:
      findAllForKey in interface GenericCompositeKeyFilterableDao<T extends net.solarnetwork.dao.Entity<K>,K extends CompositeKey2<K1,K2>>
      Parameters:
      filter - the key that acts like a filter to restrict the results to
      sorts - list of sort descriptors to sort the results by
      Returns:
      list of all persisted entities, or empty list if none available
