The Decorator Design Pattern is a structural design pattern that allows behavior to be added to individual objects dynamically, without affecting the behavior of other objects from the same class1. This pattern is particularly useful when you need to add functionality to objects in a flexible and reusable way.
Key Components
The Decorator Pattern involves several key components:
Component Interface: This is an abstract class or interface that defines the common interface for both the concrete components and decorators. It specifies the operations that can be performed on the objects1.
Concrete Component: These are the basic objects or classes that implement the Component interface. They are the objects to which we want to add new behavior or responsibilities1.
Decorator: This is an abstract class that also implements the Component interface and has a reference to a Component object. Decorators are responsible for adding new behaviors to the wrapped Component object1.
Concrete Decorator: These are the concrete classes that extend the Decorator class. They add specific behaviors or responsibilities to the Component. Each Concrete Decorator can add one or more behaviors to the Component1.
