Structural Design Patterns in Modern C++ - Class Adapter

The video tutorial explains the implementation of a class adapter in a project. It begins with setting up a new project and modifying the accelerometer class to motivate the use of a class adapter. The tutorial contrasts object and class adapters, highlighting the limitations of object adapters. It then details the steps to implement a class adapter, including customizing initialization values and updating the class diagram. The advantages of using a class adapter, such as overriding inherited functions and using private inheritance, are also discussed.

What is the primary motivation for using a class adapter in the project?

• To modify the existing project directly

• To change the accelerometer class values

• To use hard-coded values in the accelerometer class

• To add a new project without modifying the existing one

What is the purpose of the initialize function in the accelerometer class?

• To return a pair of values for initialization

• To hard-code the values

• To remove the need for a virtual function

• To change the output of the application

Why is the object adapter not sufficient for the flight simulator game?

• It cannot be used with a class adapter

• It changes the output of the application

• It requires hard-coded values

• It does not allow customization of initializer values

What change is made to the axial adapter class to transition from object adapter to class adapter?

• Removing the accelerometer

• Inheriting from the accelerometer

• Adding a new method to the accelerometer

• Composing the accelerometer

What is one advantage of using a class adapter over an object adapter?

• It exposes all methods of the base class

• It allows for private inheritance

• It requires more code

• It cannot override inherited functions

How can you prevent the methods of the adaptee from being exposed through the adapter?

• By composing the adaptee

• By using private inheritance

• By using public inheritance

• By not inheriting from the adaptee

What is a key benefit of using a class adapter in terms of functionality?

• It eliminates the need for inheritance

• It enables overriding of adaptee functions

• It allows for hard-coding values

• It simplifies the class diagram
