Java Adapter Mode
Recent Learning Java Basics, learning the adapter when puzzled a lot of information on the Internet to check the data, for adapter a lot of information, but the comparison of this article is good, here records, we need to see.
Adapter mode is to transform the interface of a class into another interf

Adapter mode Adapter): Converts an interface of a class to another interface that the customer wants. The A d a p t e r mode makes those classes that cannot work together due to interface incompatibility work together.
Applicable scenarios:
1. Existing class interfaces do not meet our needs;
2. Create a reusable class so that the class can work collaboratively with other unrelated classes or unforeseen clas
The following figure shows the class adapter and Object Adapter. The adapter mode is used to solve the problem of using incompatible interfaces. The following shows that the two adapters have three classes: Target, adaptee, and adapter.The client wants to use target. Request ()The existing classes use adaptee. specificrequest ()Request () and specificrequest () m
During the installation of 11g, this machine encountered the need to install the loop adapter. My system is Windows 2003 Server. in the network environment of the lab, IP addresses are automatically allocated by DHCP. If Oracle finds that your machine is using DHCP, install the Microsoft loopback adapter to provide a static IP address. For details about the installation method, see:

Next, I will use a simple demo to illustrate the adapter mode and first look at a picture (not to implement the above example)

Adapter Mode definition: Jiuge two incompatible classes together, in a structured pattern, with two identities (adaptee) and adaptor (adapters). Why use adapter mode we often encounter the need to combine two classes that are not related to each other, the first solution is to modify the interfaces of the respective classes, but if we do not have the source code, or we do not want to modify the respective i
The adapter mode transforms 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.Structure of the adapter patternThe adapter mode has two different forms of adapter mode for the class and
Adapter mode (Adapter pattern)——. NET design Pattern series eightTERRYLEE,2006 year FebruaryOverviewIn the software system, because of the change of the application environment, it is often necessary to put "some existing objects" in the new environment, but the interfaces required by the new environment are not satisfied by these existing objects. So how do you deal with this "migration change"? How can yo
I. Introduction
In the actual development process, due to the changes in the application environment, such as the changes in the use language), we need to implement that there is no existing object in the new environment to meet, however, such existing objects exist in other environments. So what if we call "existing objects" in the new environment? The solution to this problem is the adapter mode we will introduce in this article --In this way, exist
Structural patterns (structural pattern) describe how a class or object can be combined to form a larger structure. The structure pattern describes two different things: a class and an instance of a class. According to this point, the structure pattern can be divided into the structure pattern of the class and the structure pattern of the object.

1. Model Introduction
Definition of the 1.1 pattern:
The adapter pattern transforms the interface of a class into another interface that the client expects, so that two classes that cannot work together because of an interface mismatch can work together.
1.2 Usage Scenarios for mode:
U
The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that the original interface does not match and cannot work together can work together.

Overview
In software systems, due to changes in the application environment, we often need to put "some existing objects" in the new environment for application, however, the interfaces required by the new environment are not met by these existing objects. So how should we deal with this "Migration change "? How can we make good use of the existing object and meet the interfaces required by the new application environment? This is the Adapter mode des
Problem Introduction: for example, if there are A-type and B-type nuts, you can directly use A-type screws produced by A-type nuts on a-type nuts, you can also directly use B-type screws produced according to B-type Nut standards on B-type nuts. However, because a-type nut and B-type nut have different standards, you cannot directly use B-type screws on A-type nut, and vice versa. How can we achieve this goal?
You can solve this problem by using an adapter

GOF "design pattern" is described in the adapter mode:
Converts the interface of a class into another interface that the customer expects. The adapter mode makes it possible for classes that cannot work together because of incompatible interfaces.
This passage roughly says: We need a way to create a new interface for an object that is functionally correct but not interface. For example, customers give us
