Design patterns provide a reliable and easy way to follow proven design principles and to write well-structured and maintainable code. Adapter pattern works as a bridge between two incompatible interfaces. He asked Mr. Y to assume that there are 5 services, 25 operators, 29 circles and 3 providers. A real life example could be a case of card reader which acts as an adapter between memory card and a laptop. ... the adapter pattern is a software design pattern that allows the interface of an existing class to be used as another interface. You have a team of two developers, A & B (specialist in ASP.NET), who work on this client's project directly, without your involvement. Most of the code is boilerplate. The name says it all. Now let’s look at an example to see how adapter pattern works. Let’s get to exploring the template method pattern with both a real world example, as well as a functional C# sample! From the lower diagram, the adapter contains an instance of Orange, and extends Apple. This pattern involves a single class called adapter which is responsible for communication between two independent or incompatible interfaces. You can have a DAO interface that all other DAO classes implement. In order to make different electrical sockets work together with a different plugs the use of adapters is necessary. The Adapter idea can be demonstrated with the following simple example. Then Mr. X explains the real-world situation. Real-world examples might be a language translator or a mobile charger… Then you can implement a Transaction Decorator that wraps each call to the DAO … Interfaces may be incompatible but the inner functionality should suit the need. Adpater Pattern Real World Example. ... Real world example. The adapter pattern convert the interface of a class into another interface clients expect. The purpose of the sample problem is to adapt an orange as an apple. Adapter design pattern is used when you want two different classes with incompatible interfaces to work together. For example, in Zend Framework, all the Adapter classes are in fact implementations of the Strategy pattern, because they only wrap native code behind classes, to have several behaviours. Class Adapter A real-world example You work on a client's projects. Design Patterns Explained – Adapter Pattern with Code Examples. It can also lead to hard to trace bugs. This is the real world definition for an adapter. So the mobile charger works as an adapter between mobile charging socket and the wall socket. The name says it all. You plugin the memory card into card reader and card reader into the laptop so that memory card can be read via laptop. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces. I use my monitor in different ways which you can see in the following image. Interfaces may be incompatible but the inner functionality should suit the need. Class Diagram: The client sees only the target interface and not the adapter. Mobile battery needs 3 volts to charge but the normal socket produces either 120V (US) or 240V (India). Let’s see the implementation of Adapter pattern in C#, with IDbDataAdapter example, By using the adapter client is able to use the existing functionality provided by the Adaptee class. Example: Suppose you have a Bird class with fly() , and makeSound…
