Instance Method Details

#code=(val) ⇒ Object

When code is assigned, eagerly populate text from Isoics if no explicit text has been set. Going through the public writer registers the value with the lutaml-model ‘value_set_for` tracker so the attribute is emitted on serialization.

def code=(val)
  super
  return unless val.is_a?(String) && !val.empty?
  return if @text.is_a?(String) && !@text.empty?

  description = Isoics.fetch(val)&.description
  self.text = description if description
end

#text ⇒ Object

Returns the explicit text if set, else the Isoics description for ‘code`. Kept for consumers that read `.text` directly.

def text
  return @text if @text.is_a?(String) && !@text.empty?

  Isoics.fetch(code)&.description if code.is_a?(String) && !code.empty?
end

#using_default_for(attribute_name) ⇒ Object

When the deserializer reaches the end of the XML element and records that <text> was absent, it calls ‘using_default_for(:text)` to mark the attribute as default-valued (suppressing serialization). Refuse that mark if we’ve already populated text from Isoics so the value survives round-trip. See #112.
