Zasady wizualizacji w Scala<\/h2>\n

W VPasCode, renderowanie Scala automatycznie analizuje class<\/code>, case class<\/code>, trait<\/code>, cecha zamkni\u0119ta<\/code>, oraz object<\/code> definicje na strukturalne karty diagram\u00f3w w stylu UML. Cechy i klasy przypadkowe dzia\u0142aj\u0105 jako g\u0142\u00f3wne w\u0119z\u0142y domeny, pola parametr\u00f3w s\u0105 wymieniane jako atrybuty typowane, a s\u0142owa kluczowe dziedziczenia lub implementacji cech generuj\u0105 jasne linie relacji strukturalnych mi\u0119dzy jednostkami wizualnymi.<\/p>\n

1. Podstawowa konfiguracja<\/h3>\n

Aby wizualizowa\u0107 standardowy model domeny w Scala, zdefiniuj cechy zamkni\u0119te dla zamkni\u0119tych hierarchii typ\u00f3w wraz z konkretnymi klasami przypadkowymi.
