Decorator

In the last chapter, we covered a range of design patterns, including the Prototype design pattern. The Prototype pattern is particularly useful for creating class instances with varying data attributes. But what if our goal extends to developing a collection of classes, each with its own unique behavior?

This section introduces an alternative method for a similar objective. It’s important to remember that design patterns offer a variety of solutions to common software development problems.

By implementing the Decorator design pattern, we empower users of our code to specify the abilities they want to add to their objects. This approach offers a flexible way to extend the behavior of classes without modifying their structure directly.

Having understood the purpose of the Decorator pattern, let’s now explore how it can be applied to augment a class.

Enhancing a class

Let’s consider a straightforward class that registers all the captains...
