Adapter mode (Adapter):1. Concept: Convert the interface in one class into another interface that the customer wants, so that those classes that cannot work together because of incompatible interfaces can work together.2. Role in the pattern1 target interface: the interface that the customer expects. The target can be a specific or abstract class, or it can be an interface.2 classes that need to be adapted:

As we all know, network adapter is also known as network card, is working in the link layer of networking components, is the LAN connection between the computer and transmission media interface, can achieve and LAN transmission media between physical connection and electrical signal matching.

In the words of Windows, it is to configure multiple IP for a network card.
Where to add IP aliases can be useful.
Network requirements, multiple IP access testing, specific software needs for multiple IP ... and so on.
Here are a few examples of how to use the Ifconfig command to configure an IP alias for a network adapter.

Overview
In order to meet the needs of actual projects, due to changes in the application environment, some existing objects need to be put into the new development environment, at this time, the new environment and the interface of this object cannot be directly connected, that is, they cannot know each other and exchange information. To meet this "change", how can we leverage the good implementation of existing objects, at the same time, the interface can meet the requirements of the new envir
The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that cannot work together due to interface mismatch can work together.________________________________________Usage of the adapter ModeUsing electrical appliances as an example, the plug of the laptop is generally three-phase, that is, in addition to the anode and cathode, there is also
In the book "Java and Patterns" of Dr. Shanhong, this describes the adapter (Adapter) Pattern: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.

Overview:
In the process of software development, we often need to reuse some of the "existing objects" we have previously developed, but these "existing objects" cannot meet our new application environment. How can we reuse these objects well to meet our application environment? This is what the adapter is trying to solve.
Intent:Converts an interface of a class to another interface that the customer wants. The
A communicator contains one or more object adapters. an Object Adapter sits at the boundary between the ice run time and the server application code and has a Number of responsibilities: • It maps ice objects to servants for incoming requests and dispatches the requests to the application code in each servant (that is, an Object Adapter implements an up-call interface that connects the ice run time and

DescriptionIn order to solve the problem of incompatible interfaces the introduction of an interface compatibility mechanism, is the adapter mode, which provides an adapter class to convert the interface provided by a third party to the client's desired interface. Examples of life: mobile phone charger to convert 220v power supply to the appropriate voltage to the phone to charge. This charger is the right
