Overview

Immutable representation of a yaml_structure do ... end block.

  • klass — the ActiveRecord class this structure is attached to. Resolved lazily: the constructor accepts either a class or a callable, and defers to first access. This matters for inner structures whose class might be resolved via a reflection that isn't safe to compute at declaration time (anonymous parent classes, etc.).
  • nodes — ordered list of node objects. Order matches declaration and drives export key order.
