  @content = gen_content(xml_path)
  extension_id = @module_name

  if loaded_extensions.key?(extension_id)
    raise ArgumentError,
          "Extension '#{extension_id}' is already loaded from " \
          "'#{loaded_extensions[extension_id]}'. " \
          "Call unload_extension('#{extension_id}') first if you want to reload it."
  end

  Object.class_eval @content
  update_mappings(extension_id)
  loaded_extensions[extension_id] = xml_path
end

.loaded_extensions ⇒ Hash<String, String>

List all currently loaded extensions.

Returns:

  • (Hash<String, String>) —

    Map of extension_id => xml_path

end

.unload_extension(extension_id) ⇒ void

This method returns an undefined value.

Unload an extension by removing its module and clearing tracking.

This allows the extension to be loaded again, which is useful for testing scenarios that need to reload extensions.

Parameters:

  • extension_id (String, Symbol) —

    The extension module name (e.g., “Citygml”)
