Factory patterns concern themselves with object creation.

abstract factory

• 11:50-15:10 factory patterns: What problem they solve

• 16:20-19:50 the abstract factory solution

Using one make method.

• 24:30-36:50 the boundary dilemma
  • 32:10-33:00 type safety relies upon coupling, and cannot be used across architectural boundaries.
  • 33:00-36:50 type safety vs independent developability
• 47:26-47:50 Test-driven development protects you from the small amount of type safety lost by using one method with string parameter.

Variations: Factory Method

• 47:50-50:30 Pattern variations: The factory method
• 50:30-51:30 factory method vs abstract factory tradeoffs
