Design Patterns

Design patterns are typical solutions to common software problems.

Creational Patterns

  • Deal with the creation/construction of objects
  • Explicit (constructor) vs. Implicit (DI, reflection, etc.)
  • Wholesale (single statement) vs. Piecewise (step-by-step)
  1. Builder Pattern
  2. Factory Pattern
  3. Prototype Pattern
  4. Singleton Pattern

Structural Patterns

  • Concerned with the structure (e.g., class members)
  • Many patterns are wrappers that mimic the underlying class' interface
  • Stress the importance of good API design
  1. Adapter Pattern
  2. Bridge Pattern
  3. Composite Pattern
  4. Decorator Pattern
  5. Facade Pattern
  6. Flyweight Pattern
  7. Proxy Pattern
