Adapter Pattern In C

The idbdataadapter interface inherits from the idataadapter interface and allows an object to create a dataadapter designed for use with a relational database.

Adapter pattern in c. The adapter pattern is usually used when you don t have control over the target class. These incompatible classes may come from different libraries or frameworks. In such cases adapters make legacy code with modern classes. Adapter pattern is placed under the category of structural design pattern.

In this article i would like share what is adapter pattern and how is it work. It can increase a code complexity by adding additional classes adapters but it is worth an effort for sure. This structural code demonstrates the adapter pattern which maps the interface of one class onto another so that they can work together. The adapter pattern is adapting between classes and objects.

My primary use of the adapter pattern would be to create wrappers for a framework class that doesn t implement an interface. Like any adapter in the real world it is used to be an interface a bridge between two objects. In this article i would try to explore a very useful and commonly used design pattern the adapter pattern. Say i want to mock out a framework class which doesn t implement an interface and doesn t have virtual methods.

Probably everyone have seen some adapters for memory cards. Adapter pattern falls under structural pattern of gang of four gof design patterns in net. I will cite my examples using c language. It is often used to make existing classes work with others without modifying their source code.

Structural code in c. An example is an adapter that converts the interface of a. The adapter pattern is pretty common in c code. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces.

In real world we have adapters for power supplies adapters for camera memory cards and so on. Adapter as the name suggests is the object which lets two mutually incompatible interfaces. This pattern involves a single class which is responsible to join functionalities of independent or. It is especially used for toolkits and libraries.

Adapter is recognizable by a constructor which takes an instance of different abstract interface type. Adapter pattern works as a bridge between two incompatible interfaces. The adapter pattern is pretty common in the c world and it is quite used when we have to adapt some existing classes to a new interface. When the adapter receives a call to any.

It s very often used in systems based on some legacy code.
