Overview

Builds an OpenEHR::AQL::Dataset (the AQL engine's only input boundary) out of the RM graph. Feeds it real OpenEHR::RM objects via Rm::Composition#to_rm (RmObjectBuilder) rather than the rm_composition JSON cache, because OpenEHR::RM::CompositionFactory.create_from_json does not recursively convert array-valued attributes (content/events/ items) into RM objects -- see doc/HANDOFF_openehr_aql_create_from_json.md and spec/openehr_rails/rm/create_from_json_roundtrip_spec.rb.

Instance Method Details

#call ⇒ Object

Dataset.new never iterates eagerly, so this stays lazy end to end: constructing it issues no queries; each Enumerator::Lazy chain below only runs when the caller actually walks #each_ehr.
