Defined in:
lib/xmi/sparx/index.rb

Overview

Builds all commonly needed indexes from a parsed SparxRoot in a single targeted walk, avoiding the generic map_id_name approach that visits every attribute of every node.

Indexes built:

  • id_name_map: { xmi_id => name } for all nodes with both id and name

  • packaged_elements: flat array of all PackagedElement instances

  • packaged_by_id: { xmi_id => PackagedElement }

  • packaged_by_type: { “uml:Class” => […], “uml:Package” => […], … }

  • upper_level_map: { xmi_id => parent PackagedElement }

  • elements_by_idref: { idref => Extension::Element::Element }

  • connectors_by_idref: { idref => Connector::Connector }

  • attributes_by_idref: { idref => Extension::Element::Attribute }

  • owned_attrs_by_type_idref: { type_idref => [OwnedAttribute, …] }
