What are the types of Adapter patterns?
structural pattern
Adapter pattern works as a bridge between two incompatible interfaces. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces.
What is Adapter pattern give an example of adapter pattern?
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.
What is adapter pattern explain?
An Adapter pattern acts as a connector between two incompatible interfaces that otherwise cannot be connected directly. An Adapter wraps an existing class with a new interface so that it becomes compatible with the client’s interface.
What problems does the adapter pattern solve?
The adapter design pattern solves problems like:
- How can a class be reused that does not have an interface that a client requires?
- How can classes that have incompatible interfaces work together?
- How can an alternative interface be provided for a class?
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 Adapter also known as?
Adapters (sometimes called dongles) allow connecting a peripheral device with one plug to a different jack on the computer. They are often used to connect modern devices to a legacy port on an old system, or legacy devices to a modern port. Such adapters may be entirely passive, or contain active circuitry.
Which is an example of an adapter design pattern?
Let’s understand the example of adapter design pattern by the above UML diagram. There are the following specifications for the adapter pattern: Target Interface: This is the desired interface class which will be used by the clients.
What do you mean by adapter pattern in Java?
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 are the two types of adapter in Java?
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.
When to use composition in an adapter pattern?
The object adapter pattern that uses composition to reference an instance of the wrapped class within the adapter. You are probably aware of all the discussions about inheritance vs. composition. Composition provides more flexibility and avoids unexpected side-effect when you need to change existing code.
