CreationalPatterns

• AbstractFactoryPattern
  • Creates an instance of several families of classes
• BuilderPattern
  • Separates object construction from its representation
• FactoryMethodPattern
  • Creates an instance of several derived classes
• PrototypePattern
  • A fully initialized instance to be copied or cloned
• SingletonPattern
  • A class of which only a single instance can exist

StructuralPatterns

• AdapterPattern
  • Match interfaces of different classes
• BridgePattern
  • Separates an object’s interface from its implementation
• CompositePattern
  • A tree structure of simple and composite objects
• DecoratorPattern
  • Add responsibilities to objects dynamically
• FacadePattern
  • A single class that represents an entire subsystem
• FlyweightPattern
  • A fine-grained instance used for efficient sharing
• ProxyPattern
  • An object representing another object

BehavioralPatterns

• ChainOfResponsibilityPattern
  • A way of passing a request between a chain of objects
• CommandPattern
  • Encapsulate a command request as an object
• InterpreterPattern
  • A way to include language elements in a program
• IteratorPattern
  • Sequentially access the elements of a collection
• MediatorPattern
  • Defines simplified communication between classes
• MementoPattern
  • Capture and restore an object's internal state
• ObserverPattern
  • A way of notifying change to a number of classes
• StatePattern
  • Alter an object's behavior when its state changes
• StrategyPattern
