Inherits:
BaseTransformer show all
Defined in:
lib/lutaml/qea/factory/diagram_transformer.rb

Overview

Transforms EA diagrams to UML diagrams

This transformer loads diagram data along with diagram objects (visual placement) and diagram links (visual connector routing) to create a complete UML diagram representation.
