C++ implementation of some design patterns.

• Composite

  • Treat individual objects and compositions of objects uniformly.
  • Useful to represent hierarchies of items

• Double Dispatch

  • Basic mechanism of the Visitor pattern.
  • Understanding double dispatch means understanding Visitor

• Composite Visitor

  • A perfect match of two patterns (Composite and Visitor)
  • Useful to represent and process hierarchies of items

• State

  • Represents a finite state machine (FSM)
  • Very similar to the Strategy pattern, just different intent

• Event Notifier

  • Based on "Event notifier: a pattern for event notification"
  • (implemented in Java)

• Perception

  • Application of Abstract Factory, Composite, and Visitor
  • (works on Linux and OSX)
