  1. Template Method - UML

  2. Alarm Clock Radio

  3. Alarm Clock Radio • Not Template • No Inheritance • Aggregation is the wrong way

  4. Alarm Clock

  5. Alarm Clock Radio • Not a Template • Multiple Inheritance

  6. Car Builder

  7. Car Builder • Template Pattern • Proper Inheritance • Primitive Operations Overloaded (BuildSkeleton, InstallEngine, InstallDoor) • BuildCar is the Template Method Template Method Primitive Operations Inheritance

  8. Person

  9. Person • Template Pattern • Proper Inheritance • Primitive Operations Overloaded (washUp, eatBreakfast) • feedDog & getReadyToLeaveHouse are the Template methods • Dress is a hook Template Method Hook Primitive Operations Inheritance

  10. Command Pattern – UML

  11. Stocks

  12. Stocks • Command Pattern • Note Typo in Day section • Client – Agent • Callback Interface – placeOrder • Callback 1 & 2 – SellStockOrder& BuyStockOrder • Receiver – StockTrade v Callback Interface Client Receiver v Callback Interface

  13. Bridge UML

  14. Bridge UML • Definition: Decouple an abstraction from its implementation so that the two can vary independently • Used to prevent a combinatorial explosion of classes. • If a change to one class causes multiple classes to be created, then you probably aren’t bridging properly • Just because to class hierarchies have aggregation between them doesn’t mean it’s a bridge

  15. Questions

  16. Questions Abstract Factory Version – Not a Bridge Observe how MC, TF, and Essay appear over and overObserve how Console, Audio, and Video appear over and over

  17. Survey - Questions

  18. Survey – Questions • Bridge Pattern • Abstraction – Question • Refined Abstractions – MC, Essay, TF • Implementors – Input, Output • Concrete Implementors – ConsoleInput, AudioInput, VideoInput, ConsoleOutput, AudioOutput, VideoOutput

  19. Furniture

  20. Furniture • Bridge Pattern • Abstraction – Furniture • Refined Abstractions – Sofa, Chair, SofaBed, RecliningChair • Implementors– Material, ExternalMaterial, InternalMaterial • Concrete Implementors – Wood, Metal, Leather, Cloth

  21. Survey – Questions - Bridge

  22. Survey – Questions • Bridge Pattern • Abstraction – Question • Refined Abstractions – MC, TF, Essay • Implementors – IO • Concrete Implementors – ConsoleIO, AudioIO, VideoIO

  23. Shapes

  24. Shapes • Not a Bridge Pattern • This is simply aggregation of a color into a Shape

  25. Shapes

  26. Shapes • Bridge Pattern • Abstraction – Shape • Refined Abstractions – Triangle, Square, Pentagon • Implementor– DrawingProgram • Concrete Implementors – AutoCad, Anvil

  27. Furniture

  28. Furniture • Not a Bridge pattern, Simple aggregation • both sofa and chair consist of legs, arms, and seat. If it is a bridge, then the left side should be legs, arm, seat, and the right side should be logs, fabric, etc that implements the legs and arms.

  29. Animals

  30. Animals • Not a Bridge, really a strategy • The problem is that the right side (strategy) doesn't  compose parts of the left side.
