Defined in:

lib/lutaml/model/serialize/deserialization_context.rb

Overview

Encapsulates the parent-to-child options propagation contract.

During deserialization, a parent passes context to its children via an options Hash. Only certain keys are safe to propagate — parent-internal keys (resolved_type, namespace_uri, converted) must be stripped so children derive their own context.

This class is the single source of truth for which keys propagate, replacing scattered CHILD_PROPAGATION_KEYS constants and ad-hoc ‘.slice` calls.

Usage:

child_options = DeserializationContext.propagate(options).merge(register: register)
klass.apply_mappings(value, format, child_options)

Constant Summary

PROPAGATION_KEYS =

Keys that are safe to propagate from parent to child deserialization.

Parent-internal keys (namespace_uri, resolved_type, converted, mappings) are intentionally excluded — children must derive their own context.

Class Method Summary

• .propagate(options) ⇒ Hash

  Extract propagable keys from a parent options hash.

Class Method Details

.propagate(options) ⇒ Hash

Extract propagable keys from a parent options hash.

Returns a new Hash containing only the keys safe for child deserialization. Parent-internal keys are excluded.

Parameters:

• options (Hash) —

  The parent’s options hash

Returns:

• (Hash) —

  A new hash with only propagable keys
