Review Topics

Unless otherwise specified below, know the following for each pattern mentioned here:

• goals
• be able to draw a class model applying the pattern
• explain the pro's and con's of using the pattern
• be able to write code applying the pattern

Patterns

• Creational patterns
  • Factory Method, including static factory methods
  • Builder (student presentation)
  • Prototype (student presentation)
  • Singleton
• Structural patterns
  • Adapter
  • Composite
  • Decorator
    • Not I/O decorators (at least, no expectation you will know the classes involved)

Design

• Definition of an object
• UML Notation
• Domain objects: identity, responsibility
• Noun/verb identification method
• Cohesion and coupling
• Threads, synchronization

Where to go from here?

• What would be the impact of using all the patterns on every project?
• How does coupling and cohesion relate to design patterns? Design in general?
• Is this all of the patterns? Consider the Bomb pattern
  • Pattern Languages of Programs (PLoP) conferences: annual discussion of patterns among researchers
• Why the focus on domain-driven design?
  • Basic structure: layers (Ch. 28 in Java Design Pattern Essentials)
  • Cost: potential performance impact
