Defined in:
lib/coradoc/asciidoc/model/serialization/asciidoc_transform.rb

Overview

Transform class for converting between Coradoc::Element and Lutaml::Model objects

This handles bidirectional transformation for AsciiDoc serialization:

  • data_to_model: Coradoc::Element -> Lutaml::Model::Serializable

  • model_to_data: Lutaml::Model::Serializable -> Coradoc::Element

Class Method Details

.data_to_model(context, data, _format, options = {}) ⇒ Lutaml::Model::Serializable

Convert Coradoc::Element data to Lutaml::Model instance

Parameters:

  • context (Context) —

    The context with attribute and mapping management

  • data (Coradoc::Element::Base) —

    The Coradoc element to convert

  • format (Symbol) —

    The format type (:asciidoc)

  • options (Hash) (defaults to: {}) —

    Additional options

Returns:

  • (Lutaml::Model::Serializable) —

    The model instance

end

.model_to_data(context, model, _format, options = {}) ⇒ Coradoc::Element::Base

Convert Lutaml::Model instance to Coradoc::Element data

Parameters:

  • context (Context) —

    The context with attribute and mapping management

  • model (Lutaml::Model::Serializable) —

    The model to convert

  • format (Symbol) —

    The format type (:asciidoc)

  • options (Hash) (defaults to: {}) —

    Additional options

Returns:

  • (Coradoc::Element::Base) —

    The Coradoc element
