What is the adapter pattern used for?
In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface.
What is the most common use for the adapter pattern?
The Adapter pattern is a structural design pattern that enables incompatible interfaces, from disparate systems to exchange data and work together. It is extremely useful when integrating tool-kits, libraries and other utilities together.
What is adapter pattern explain?
An Adapter Pattern says that just “converts the interface of a class into another interface that a client wants”. In other words, to provide the interface according to client requirement while using the services of a class with a different interface. The Adapter Pattern is also known as Wrapper.
What is adapter design pattern with example?
Example. The Adapter pattern allows otherwise incompatible classes to work together by converting the interface of one class into an interface expected by the clients. Socket wrenches provide an example of the Adapter. A socket attaches to a ratchet, provided that the size of the drive is the same.
When should we use adapter pattern?
Use the Adapter class when you want to use some existing class, but its interface isn’t compatible with the rest of your code. The Adapter pattern lets you create a middle-layer class that serves as a translator between your code and a legacy class, a 3rd-party class or any other class with a weird interface.
How do adapter patterns work?
The adapter pattern convert the interface of a class into another interface clients expect. Adapter lets classes work together that couldn’t otherwise because of incompatible interfaces. The client sees only the target interface and not the adapter. Adapter delegates all requests to Adaptee.
Are Android adapters An example of adapter design pattern?
No, they aren’t. The GoF Adapter is used when you need to convert an interface between two types that are similar but not the same.
When should we use Adapter pattern?
What are the two variations of adapter pattern?
If you do some research on the adapter pattern, you will find two different versions of it: The class adapter pattern that implements the adapter using inheritance. The object adapter pattern that uses composition to reference an instance of the wrapped class within the adapter.
What are adapters in Android?
An Adapter object acts as a bridge between an AdapterView and the underlying data for that view. The Adapter provides access to the data items. The Adapter is also responsible for making a View for each item in the data set.
What is true about Adaptor pattern?
Adapter pattern works as a bridge between two incompatible interfaces. This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces. A real life example could be a case of card reader which acts as an adapter between memory card and a laptop.
