Однонаправленные ассоциации

Для создания подобной связи Rose генерирует специальные атрибуты. Естественно, что при подобной ассоциации связь генерируется только для одного класса. При этом Rose генерирует закрытый атрибут (Private). В остальном генерация происходит так же как и в наследовании (связь показывается стрелкой Unidirectional Association). Ниже показана картинка отношения и код, сгенерированный Rose (далее в статье также будет использоваться такой же подход: описание связи, рисунок связи, сгенерированный файл заголовка).
