Biztalk's TCP/IP adapter was initially developed for the health care industry in the UK. This adapter is an adapter in the BizTalk process. It connects messages to the remote client through TCP/IP string.
TCP/IP adapters support the following interactive modes:
Request only messages are sent to BizTalk and routed to any process (orchestration) or sending port.
In Android programming, various adapters are everywhere, and their complicated design is amazing!
Based on your own experience, let's talk about the adapter design mode.

The adapter mode is to convert an interface of a class to another interface that the customer wants, so that those classes that cannot work together due to incompatibility of the interface can work together.

We often encounter such a situation that there are two ready-made classes with no connection between them, but now we want to use one of the class methods, I also want to use another class method. One solution is to modify their respective interfaces, but this is what we are most reluctant to see. At this time, the Adapter mode will be used.

What is adapter mode?Convert the interface of one class to another interface that the customer wants, so that classes that are not working together because they are incompatible can work together.What scenario uses the adapter mode?For example, we have to re-use some of the early code or third-party libraries or other maintenance of the code, but the interface of the code and we are not compatible with the
Introduction of Adapter ModeThe main problem with adapter mode is that this interface type does not meet the current requirements when the existing interface type needs to be called. You need to create an adapter to convert the existing interface type, which is converted to the purpose of the new demand call. Adapters only serve the purpose of a functional conver
Points:
1. The adapter pattern is primarily used in situations where "you want to reuse some existing classes, but interfaces are inconsistent with the reuse environment", which is useful in legacy code reuse, class library migrations, and so on.
2. Adapter mode has two forms of object adapter and class adapter implem

Perhaps you would say, since there is only one way to modify, then there is no harm to modify it, we assume that there are 100 interfaces between the hall program and the game program, most of which are modified? Because of the modification of the Game program Interface, the hall program may have to be modified in more t

The adapter mode is a very understandable mode, which is also very common in life. What Plug 2 ports to 3 Ports, what USB to PS2, This is the adapter mode. To put it bluntly, if you have some interfaces that provide a lot of functionality, but you don't have a good interface to use, you need an adapter, c
The adapter mode can be used to adapt between the current interface and incompatible classes.
Objects that use this mode are called wrapper because they are packaging another object with a new interface.
When designing a class, you often encounter situations where some interfaces cannot be used together with existing APIs. By using the adapter, you can use these classes without directly modifying them.
