By routing a filtered, grouped, ordered and paged read request over Dao<TEntity, TEntityCollection, TDataContext, TFilteringCriteria, TOrderingCriteria, TPagingCriteria, TCarboniteController, TTransaction, Entities, this inversion control method handles the request to obtain IGrouping<object, TEntity> aggregations composed of all TEntity entities in the read segment defined by Paging and in compliance with the filtering criteria, then grouped according to the grouping criteria and finally sorted in the order defined by the OrderingCriteria<TEntity> set.
