Key Components of the Decorator Design Pattern
- 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 objects.
- 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 responsibilities.
- 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 object.
- 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 Component.
Decorator Design Pattern
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 class. It involves creating a set of decorator classes that are used to wrap concrete components.
