Milestone 2 Requirements

For this milestone, you will be creating additional classes to represent the entrées, and drinks served at “Dogs ‘N Such”, and refactoring some of your existing classes to take advantage of polymorphism. These will be created within the Data project of the solution you accepted from GitHub classroom.

General requirements:

• You need to follow the style laid out in the C# Coding Conventions

• Create classes that reflect the specifications given below

  • Create specialty dog classes

  • Create Drink class

  • Create DrinkFlavor Enum

• All classes should be declared in their respective namespace (see below)

Assignment requirements:

• Refactored Dog class (1)
• Specialty Dog classes (7)
• Side Base class (1)
• Refactored side classes (4)
• DrinkFlavor Enum (1)
• Drink class (1)

Purpose:

Exploration of how object-oriented polymorphism can reduce the amount of code you need to write and increase the maintainability of the code you do. We are also practicing refactoring (re-writing existing, functional code to be more legible, efficient, and maintainable). Also, more practice writing methods and properties and using enumerations.

Recommendations:

• Get in the habit of reading the entire assignment before you start to code. Make sure you understand what is being asked of you. Please do not stub your toe and have to redo work because you did not read the entire assignment.

• Accuracy is important. Your class, property, enumeration and other names, along with the descriptions must match the specification given here. Otherwise, your code is not correct. While typos may be a small issue in writing intended for human consumption, in computer code it is a big problem!

• Remember that you must document your classes. This includes a general identity comment at the top of your files, i.e.:

Dog Classes

While Dogs ‘N Such prides itself on its customizable hot dog, it also offers a selection of regional specialty hot dogs that are pre-configured with certain ingredients. As these are still hot dogs, it makes sense to extend the Dog class and create a derived class for each specialty dog.

These additional classes should also be declared in the DogsNSuch.Data namespace.

Refactor Dog Base Class

Because the specialty dogs will be listed on a menu, we need to add two additional properties to all dogs to support this: a Name and Description (both strings). These read-only properties needs to be added to Dog and be available with different return values in the derived classes. For the Dog class their values will be:

Name: The string "Custom Dog"

Description: The string "Made to order."

Specialty Dog Classes

For each specialty dog, you will need to create a new class that derives from the Dog class. All of these specialty dog classes should reside in the DogsNSuch.Data namespace

The Dogs N’ Such offers seven specialty dogs:

• Chicago Dog
• Kansas City Dog
• Polish Boy
• Seattle Dog
• Italian Dog
• Chili Dog
• Corn Dog

Chicago Dog

Implement a class to represent the Chicago Dog, named ChicagoDog in the file ChicagoDog.cs. It should have the following properties:

Name: Chicago Dog

Description: A kosher all-beef dog on a sesame-seed bun, topped with yellow mustard, chopped white onions, tomato slices, relish, a dill pickle spear, and a dash of celery salt.

It should have its Sausage property set to Sausage.Beef, its Bun property set to Bun.SesameSeed, and the boolean properties for YellowMustard, ChoppedOnion, TomatoSlices, SweetRelish, DillSpear, CelerySalt all set to true. Other boolean properties should be false.

Kansas City Dog

Implement a class to represent the Kansas City Dog, named KansasCityDog in the file KansasCityDog.cs. It should have the following properties:

Name: Kansas City Dog

Description: A pork sausage in a sesame seed bun topped with brown mustard, sauerkraut, and melted swiss cheese.

It should have its Sausage property set to Sausage.Pork, its Bun property set to Bun.SesameSeed, and the boolean properties for BrownMustard, Sauerkraut, SwissCheese all set to true. Other boolean properties should be false.

Polish Boy

Implement a class to represent the Polish Boy, named PolishBoy in the file PolishBoy.cs. It should have the following properties:

Name: Polish Boy

Description: A kielbasa sausage in hoagie bun topped french fries and BBQ Sauce.

It should have its Sausage property set to Sausage.Kielbasa, its Bun property set to Bun.Hoagie, and the boolean properties for FrenchFries, BBQSauce, Coleslaw all set to true. Other boolean properties should be false.

Seattle Dog

Implement a class to represent the Polish Boy, named SeattleDog in the file SeattleDog.cs. It should have the following properties:

Name: SeattleDog

Description: A kielbasa sausage in hoagie bun topped with cream cheese and sauteed onions.

It should have its Sausage property set to Sausage.Kielbasa, its Bun property set to Bun.Hoagie, and the boolean properties for CreamCheese and SauteedOnion all set to true. Other boolean properties should be false.

Italian Dog

Implement a class to represent the Italian Dog, named ItalianDog in the file ItalianDog.cs. It should have the following properties:

Name: Italian Dog

Description: A pork frank fried in pizza bread and topped with fried bell peppers, onions, and potatoes.

It should have its Sausage property set to Sausage.Pork, its Bun property set to Bun.PizzaDough, and the boolean properties for FriedPepper, FriedOnion, and FriedPotatoes all set to true. Other boolean properties should be false.

Chili Dog

Implement a class to represent the Chili Dog, named ChiliDog in the file ChiliDog.cs. It should have the following properties:

Name: Chili Dog

Description: A beef frank on a hoagie bun toped with chili, cheddar cheese, and diced onion.

It should have its Sausage property set to Sausage.Beef, its Bun property set to Bun.Hoagie, and the boolean properties for Chili, CheddarCheese, and ChoppedOnion all set to true. Other boolean properties should be false.

Corn Dog

Implement a class to represent the Corn Dog, named CornDog in the file CornDog.cs. It should have the following properties:

Name: Corn Dog

Description: A beef frank fried in corn breading, and served with yellow mustard.

It should have its Sausage property set to Sausage.Beef, its Bun property set to Bun.CornBreading, and the boolean property for YellowMustard set to true. Other boolean properties should be false.

Hints

• Remember that the derived classes inherit all properties and methods of the base class. This means you don’t need to re-create properties!
• Specialty Dog customizations are most easily accomplished by creating a constructor in each of your derived classes, though there are other possible approaches.
• Name and Description should be read-only, but need to have different values in the derived classes than the base class. What mechanism(s) can be used for this?

Side Classes

Armed with our new understanding of inheritance, we can see that the Side classes each share properties (for example, they each have a Size property and the prices are the same across all sides). We could move these properties to a base class, much like we use the Dog class for our hot dogs. However, there is no generic “side” the same way there is a classic “hot dog”, so we’ll want to make this one abstract.

Side Base class

Create a new class, Side to serve as a base class for each of your sides in the Side.cs file. It should be declared abstract, and have abstract read-only properties for Name and Description (both strings). It should also have properties for Calories (a uint), Price (a decimal), and Size (a Size).

Refactor Side classes

Refactor your four side classes to inherit from Side. This may allow you to remove duplicate code from the derived classes!

The Name property of the side should be the name in human case (not Pascal or Camel Case), and be proceeded with the size, i.e. “Large French Fries”. Refer to the table below for clarity.

The Description property should also match that given in the table below.

* Where [size] is the size of the side.

Hints

• Remember the override keyword is used to replace the implementation of properties and methods in derived classes, but it can only be used in conjunction with properties or methods declared virtual, abstract, or override.
• The virtual keyword allows you to declare an implementation in the base class that can be overridden
• The abstract keyword allows you to declare a method or property that is not implemented in an abstract base class, but must be overridden in the derived class.

Drink Class and Enum

Finally, you will need to create a class to represent the drinks available at Franks ‘N Such. Franks ‘N Such only carries 8.1oz cans, so the class is straightforward. Instead of using derived classes like we did with the dog classes, we’ll use an enumeration to represent the possible flavors.

DrinkFlavor Enum

Declare an enumeration to list the flavors of drink available. These are:

• RCCola
• CherryRCCola
• SevenUP
• BigRed
• DrPepper

Drink Class

Declare a implement a class Drink in the file Drink.cs in the DogsNSuch.Data namespace that represents the drinks available at Dogs ‘N Such. It should have the following properties:

Flavor: An property with the DrinkFlavor enum type. It should default to DrinkFlavor.RCCola.

Name: A read-only string property that is a string representing the name of the drink, i.e. "RC Cola" for DrinkFlavor.RCCola. It should be in human-readable form (i.e. not camel case or Pascal case). The exact spelling is found in the table below.

Description: A read-only string property which is "8.1oz can" followed by the name of the drink, i.e. "8.1oz can RC Cola"

Price: A read-only decimal representing the price of the drink. All drinks are $1.50.

Calories: A read-only uint representing the calories in the drink, which varies according to the flavor. The various values can be found in the table below:
