        public org.molgenis.data.Entity findOneById​(Object id)
        Retrieves a single entity by id.
        Specified by:
        findOneById in interface org.molgenis.data.Repository<org.molgenis.data.Entity>
        Overrides:
        findOneById in class org.molgenis.data.AbstractRepositoryDecorator<org.molgenis.data.Entity>
        Parameters:
        id - the entity's ID value
        Returns:
        the retrieved Entity, or null if not present.

      • findAll

        public Stream<org.molgenis.data.Entity> findAll​(Stream<Object> ids)
        Retrieves multiple entities by id.

        If the repository is cacheable and the current transaction hasn't completely dirtied it, will split the stream into batches and load the batches through findAllBatch(List).

        Otherwise, will delegate this call to the decorated repository.

        Specified by:
        findAll in interface org.molgenis.data.Repository<org.molgenis.data.Entity>
        Overrides:
        findAll in class org.molgenis.data.AbstractRepositoryDecorator<org.molgenis.data.Entity>
        Parameters:
        ids - Stream of ids to retrieve
        Returns:
        Stream of retrieved Entitys, missing ones excluded
