The Decorator Pattern provides a flexible alternative to sub classing for extending functionality dynamically.The following class diagram shows us the Decorator Pattern's design:A decorated class is a base class of concrete decorator classes and it inherits from the base component class. this is a nice solution to a different problem, but this is not a "truly" decorator pattern, this design is missing the decorator class that is inherited by any decorator in this case printer and CD drive – Roger Rabbit Mar 2 '14 at 9:51 The decorator pattern is structurally nearly identical to the chain of responsibility pattern, the differenc The classes and objects participating in this pattern are: Component (LibraryItem) defines the interface for objects that can have responsibilities added to them dynamically. Decorator Pattern The Decorator Pattern provides a flexible alternative to sub classing for extending functionality dynamically. This article describes the Decorator Pattern. Please read our previous article where we discussed the Facade Design Pattern in C# with examples. Using decorators you can wrap objects countless number of times since both target objects and decorators follow the same interface. Decorator pattern allows a user to add new functionality to an existing object without altering its structure. Hooray! The idea of the Decorator Pattern is to wrap an existing class, add other functionality to it, then expose the same interface to the outside world. In object-oriented programming, the decorator pattern is a design pattern that allows behavior to be added to an individual object, dynamically, without affecting the behavior of other objects from the same class. In this article, I am going to discuss the Decorator Design Pattern in C# with some examples. The Decorator design pattern is quite popular in C# due to the fact that it helps us dynamically add behaviors to the wrapped objects. The Decorator Design Pattern falls under the category of Structural Design Pattern. ConcreteComponent (Book, Video) defines an object to which additional responsibilities can be attached. Decorator is a Conceptual pattern that allows adding new behaviors to objects dynamically by placing them inside special wrapper objects.. Decorator (Decorator) This type of design pattern comes under structural pattern as this pattern acts as a wrapper to existing class. used to add new functionality to an existing object without changing its structure The decorator pattern is often useful for adhering to the Single Responsibility Principle, as it allows functionality to be divided between classes with unique areas of concern. The resulting object will get a stacking behavior of all wrappers. So the decorators can be used in the place of concrete components.BasicAccessories : CarAccessoriesDecorator,AdvancedAccessories : CarAccessoriesDecorator,SportsAccessories : CarAccessoriesDecorator,pubic classs ExtremeSportAccessories : CarAccessoryDecorator.//Wrp EconomyCar instancw with BasicAccessories.CarAccessoriesDecorator objAccessoriesDecorator =.//Wrap EconomyCar instance with AdvancedAccessories instance.AdvancedAccessories(objAccessoriesDecorator);+ objAccessoriesDecorator.GetDescription());Want to Become A Full Stack Developer?
