Module: Lutaml::Xml::PlanSerializer

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

Overview

Serialize-side mirror of the plan fast path: builds the output tree directly through leptris's fused create_child chain — no XmlElement tree, no DeclarationPlanner pass, no builder context stack, no moxml wrapper minting. Serialized shapes must be the plain ones (attributes, scalars, collections, nested models, raw fragments, content runs); custom-method, polymorphic, union, and multi-spelling rows keep the interpretive serializer (their output flows through hash-shaped custom APIs).

Ordered/mixed models serialize from element_order when the instance carries one (parsed models): text runs, comments, and element entries in document order, mirroring the interpretive order applier — including its content-attr-first text reads (mutations to the model show up) and CDATA flattening. Models without element_order fall back interpretively (return nil).

def call(instance, plan)
  return nil if plan[:ordered] && instance.element_order.nil?

  doc = ::Leptris::XML::Document.create
  root = doc.create_element(plan[:tree][:name])
  doc.root = root
  if plan[:ordered]
    build_ordered(root, instance, plan, doc)
  else
    build(root, instance, plan, doc)
  end
  doc.to_xml(indent: 2, no_decl: true)
end

.serializable?(plan) ⇒ Boolean

Whether the compiled plan is serialize-shaped. Ordered/mixed models serialize through build_ordered from element_order; plain models through plan rows.
