Statifier.Interpreter.Datamodel.Write (Statifier v2.0.0)

Copy Markdown View Source

What Statifier.Interpreter.Datamodel.write_location/4 wrote - a report of a write that already happened, never an instruction to perform one. path is the resolved Predicator.ContextLocation.location_path(), new_value is what was written, and prior_value is what stood at that full path immediately before the write - :undefined when nothing did, per ADR-0037's single spelling for an unbound value. This does conflate "the path was absent" with "the path held :undefined" already; that is accepted, since prior_value exists for diffing and undo, never for reconstruction.
