10. Adapter mode for JavaScript design mode ---- Adapter
The adapter mode is a very practical design mode. This article will introduce this design mode through examples.
The purpose of the adapter mode is to convert an interface of a class to another interface that the customer wants.
The
Adapter refresh data pitfall, Adapter refresh data
When the adapter refresh data, it must be able to refresh successfully, and ensure that each refresh changes the data source.
So I did this and wrote in the constructor of the adapter:
private List
Call the method in the adapter
Adapter Pattern Definition: Use two incompatible classes Jiuge, belong to the structure mode, need to have adaptee (be fit) and adaptor (adapter) two identity.
Why use Adapter mode
We often run into a combination of two classes that don't have a relationship, the first solution is to modify the interfaces of the respective classes, but if we don't have the sour
Basic of ListView-data adapter resolution and listview AdapterData adapter:
Purpose: Fill in complex data (array, linked list, database, set, etc.) on the specified view interface.ArrayAdapter (array adapter): used to bind a single data formatArray Source: can be a set or ArrayArrayAdapter (context, the layout file and data source corresponding to each list item
Explain:Transforms the interface of one class into another interface that the customer wants. Those classes that would otherwise not work together because of incompatible interfaces can work together.Solve the problem:What is needed is, but cannot be used, and cannot be modified in a short time. That is, make a function suitable for different environments.In the development, the system data, behavior are matched, but the interface does not match, you can consider the adapter.It is desirable to r
Here is a "finger-round" example to illustrate the principle of adapter mode and simple application, this example from Java and schema.

Adapter mode (Adapter pattern)IntroducedTransforms the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work together.ExampleThere is a message entity class that has the insert () and get () methods for its operat
The adapter pattern is to transform the interface of one class into another interface that the client expects, so that two classes that would otherwise not work together because of an interface mismatch can work together.An example of an adapter pattern:Please do a specific class of kittie and implement methods such as Miao (), Catchrat (), run (), sleep (), and so on. To do a puppie interface, requires WAO
Today learning another design pattern, adapter (Adapter) mode, which is a common direction, but with special requirements, is applied to this design pattern. Write here, think of a long time ago, have written an article "ASP." NET Adapter design mode (Adapter) http://www.cnblogs.com/insus/archive/2013/02/04/2891426.htm
According to the msdn webcast courses)
Adaptation: basically, the original incompatible interfaces are converted into compatible interfaces without changing the original implementations.
Gof: to convert an interface of a class to another interface required by the customer, you have to work together the classes that cannot work together due to incompatibility of the original interface.
Object Adapter:
Use an existing class as a field of the
What is the role of adapter? In fact, it is a bridge between the view interface and the data. We can be seen as an understanding of interface data binding, and the data it manipulates are generally more complex data, such as arrays, lists, databases, collections, etc.The commonly used adapters are:(1) arrayadapter; array as the data source, filled with arrayadapter(2) Simpleadapter; list as a data source, populated with Simpleadapter(3) Simplecursorad
Adapter Mode: Converts the interface of a class into another interface that the customer expects. Adapters allow classes that are incompatible with the original interface to work together.Direct. The following is the class diagram for the object adapter. Because Java does not support multiple inheritance. So this is how the Java adapter is implemented.Combining H

connect their laptops to the Internet over wireless.
However, as wireless Internet access technology becomes more and more popular, the "wireless Internet access" era has quietly come to our side. The desire to break through the limitations of Network cables and free Internet access anytime and anywhere has contributed to the growth of the wireless network card market. Now, whether wireless Internet access is available has become one of the main indicators for consumers to determine whether a c

What is adapter mode?The adapter mode makes it possible for those classes that cannot work together because of incompatible interfaces.Simply put, it is the things that need to be in front of, do not use, and short time can not transform it, so we will find a way to adapt it. The adapter pattern is primarily used in situations where you want to reuse some existin
