  1. Pattern Bridge Par Jean-Marc Boulerice 2559396 Seg3510

  2. Definition • Decouple an abstraction from its implementation so that the two can vary independently.

  3. Diagrame Uml

  4. Abstraction • Visible par les clients • Envoie les requêtes du client vers l’implementator • Fournis les fonction de haut niveau

  5. RefineAbstraction • Implémente les différentes abstraction

  6. Implementor • Interface entre plusieurs implémentation • Ne dois pas corresponde a l’interface Abstraction, peu être très différent. • Offre les opérations de bas niveau

  7. ConcreteImplementor • Implémentation de l’interface Implementor • Défini des implémentation concret

  8. Point fort • Découple l’abstraction de l’implémentation • Réduis le nombre de sous classe • Rend le code plus claire • L’abstraction et l’implémentation peuvent vraiment varier

  9. Point faible • Petite baisse de performance causer par la délégation de l’abstraction a l’implémentation
