Module: Lutaml::Xml::PlanWalk

Defined in:
lib/lutaml/xml/plan_walk.rb

Overview

Public consumer surface for the plan fast path: one engine parse + descriptor walk and direct model hydration, bypassing the wrapper-tree construction that dominates large-document consumer paths. The returned object is the mapped model root; collection attributes remain collections on that model.

.call(model_class, xml, _options = {}) ⇒ Object

Build the plan, walk the document, and hydrate the mapped root. Returns nil when the model is not plan-compilable.
