Adapter Pattern C Example

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 c example. This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces. In this article i would like share what is adapter pattern and how is it work. It is especially used for toolkits and libraries. The adapter design pattern is easy to implement and ensures calling the existing code which was otherwise difficult because their interfaces being incompatible.

Full code example in c with detailed comments and explanation. You can find an example on our singleton pattern page. In these situations it s better to apply the adapter pattern. Adapter design pattern allows a system to use classes of another system that is incompatible with it.

Net optimized code in c. Adapter pattern in c. Points of interest. To handle the incompatibility we use different approaches and based on that we can classify adapter pattern in 2 parts.

What is adapter design pattern. Adapter is most commonly known as wrappers because it wraps the adapter by a new interface which can be used by the client. Say i want to mock out a framework class which doesn t implement an interface and doesn t have virtual methods. Adapter pattern works as a bridge between two incompatible interfaces.

Convert the interface of a class into another interface that clients expect. For this example the adapter class needs to fulfill two tasks. For example the vendoradapter shown above is an object adapter because it creates an instance of object composition vendoradaptee. This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces.

Adapter pattern falls under structural pattern of gang of four gof design patterns in net. Adapter is a structural design pattern which allows incompatible objects to collaborate. Object adapter pattern. According to the gof s definition the intent of this pattern is to.

The net optimized code demonstrates the same real world situation as above but uses modern built in net features such as generics reflection object initializers automatic properties etc. The adapter play the role of converter or translator. All other patterns and much more are available in our net design pattern framework 4 5. By introducing an adapter class that implements the filtercoffeemachine interface and wraps the premiumcoffeemachine class you enable your filtercoffeeapp to use the coffee machine.

The adapter pattern is usually used when you don t have control over the target class. My primary use of the adapter pattern would be to create wrappers for a framework class that doesn t implement an interface.
