  14. case class RootEffect extends EffectMapping with Product with Serializable

    Root effects can perform an intial effect prior to computing the resulting Cursor and effective Query.

    Root effects can perform an intial effect prior to computing the resulting Cursor and effective Query.

    These effects are used to perform initial effectful setup for a query or to perform the effect associated with a GraphQL mutation. Convenience methods are provided to cover the cases where only one of the query or the cursor are computed.

    If only the query is computed the default root cursor for the mapping will be used. If only the cursor is computed the client query (after elaboration) is used unmodified ... in this case results of the performed effect can only be passed to the result construction stage via the environment associated with the returned cursor.

  9. def combineAndRun(queries: List[(Query, Cursor)]): Either[Throwable, Result[List[ProtoJson]]]

    Combine and execute multiple queries.

    Combine and execute multiple queries.

    Each query is interpreted in the context of the Cursor it is paired with. The result list is aligned with the argument query list. For each query at most one stage will be run and the corresponding result may contain deferred components.

    Errors are aggregated across all the argument queries and are accumulated on the Left of the result.

    This method is typically called at the end of a stage to evaluate deferred subqueries in the result of that stage. These will be grouped by and passed jointly to the responsible mapping in the next stage using this method. Maappongs which are able to benefit from combining queries may do so by overriding this method to implement their specific combinging logic.
