Structural patterns

In Software Engineering, Structural Design Patterns are Design Patterns that ease the design by identifying a simple way to realize relationships between entities.

  • Adapter
    Match interfaces of different classes
  • Bridge
    Separates an object’s interface from its implementation
  • Composite
    A tree structure of simple and composite objects
  • Decorator
    Add responsibilities to objects dynamically
  • Facade
    A single class that represents an entire subsystem
  • Flyweight
    A fine-grained instance used for efficient sharing
  • Private Class Data
    Restricts accessor/mutator access
  • Proxy
    An object representing another object
