Module: Coradoc::CoreModel::HasChildren

Included in:
ChildrenContent, StructuralElement
Defined in:
lib/coradoc/core_model/has_children.rb

Overview

Marker module for “this model exposes a children collection”.

Including this is the canonical way to opt a CoreModel class into children-based traversal. Downstream code (e.g. mirror’s CoreModelToMirror#element_children) dispatches on is_a?(HasChildren) rather than enumerating subclasses, so adding a new children-bearing class is purely additive (OCP).

ChildrenContent (the mixed-content auto-wrap behavior) includes HasChildren, so every class that mixes in ChildrenContent also satisfies HasChildren. Classes that carry typed block children only (StructuralElement, etc.) include HasChildren directly.
