Interface LoadIds<T>

  • All Known Subinterfaces:
    LoadType<T>
    public interface LoadIds<T>

    Terminator methods for a fetch-by-key command chain which constructs the key implicitly from type, id, and (optionally) parent.

    All command objects are immutable.

    • Method Detail

      • id

        LoadResult<T> id​(long id)

        Specify the numeric id of an entity and start asynchronous fetch.

        Parameters:
        id - - the id of the entity to fetch. Note that numeric ids and String ids are not equivalent; 123 and "123" are different ids.
        Returns:
        an asynchronous result that can materialize the entity

      • id

        LoadResult<T> id​(String id)

        Specify the String id of an entity and start asynchronous fetch.

        Parameters:
        id - - the id of the entity to fetch. Note that numeric ids and String ids are not equivalent; 123 and "123" are different ids.
        Returns:
        an asynchronous result that can materialize the entity

      • ids

        Map<Long,​T> ids​(Long... ids)

        Specify the numeric ids of multiple entities and start asynchronous fetch.

        Parameters:
        ids - - the ids of the entity to fetch. Note that numeric ids and String ids are not equivalent; 123 and "123" are different ids.
        Returns:
        a Map of the asynchronous result. The first method call on the Map will synchronously finish the call.

      • ids

        Map<String,​T> ids​(String... ids)

        Specify the String ids of multiple entities and start asynchronous fetch.

        Parameters:
        ids - - the ids of the entity to fetch. Note that numeric ids and String ids are not equivalent; 123 and "123" are different ids.
        Returns:
        a Map of the asynchronous result. The first method call on the Map will synchronously finish the call.

      • ids

        <S> Map<S,​T> ids​(Iterable<S> ids)

        Specify the ids of multiple entities and start asynchronous fetch.

        Parameters:
        ids - - the ids of the entities to fetch. The Iterator must provide Long or String. Note that numeric ids and String ids are not equivalent; 123 and "123" are different ids.
        Returns:
        a Map of the asynchronous result. The first method call on the Map will synchronously finish the call.
