Le quatrième et dernier niveau de zoom défini par le modèle C4 est le code. Ce chapitre décrit le diagramme au niveau du code qui peut être utilisé pour montrer les détails d'implémentation internes d'un composant.
Aspects clés du diagramme de code
Pour comprendre pourquoi et comment utiliser les diagrammes de code, tu dois bien saisir leur objectif, leur portée, leur contenu, leurs cas d'utilisation et leur public cible.
Objectif
L'objectif d'un diagramme de code est d'illustrer la structure du code au sein d'un composant unique, ce qui peut aider à répondre aux questions suivantes :
-
Comment un composant est-il décomposé en blocs de construction au niveau du code ?
-
Lesquels de ces blocs de construction au niveau du code sont exportés/exposés publiquement par le composant, et lesquels constituent des détails d’implémentation internes ?
-
Quelle est la taille et la complexité du composant ?
Portée
La portée d’un diagramme de code est un composant unique. Comme on va le voir tout à l’heure, un diagramme de classes UML est un bon moyen d’illustrer le code si tu utilises un langage de programmation orienté objet (POO) comme Java, C# ou C++.
Les diagrammes de classes UML ont souvent été utilisés pour décrire une application entière, mais cette approche fonctionne rarement dans la réalité. Imagine que tu aies une application ...
