Decoration Design Pattern C

I was trying to learn the decorator pattern from a well known design patterns book which provides code samples in java.

Decoration design pattern c. In this article i am going to discuss the decorator design pattern in c with some examples. Decorator can be recognized by creation methods or constructor that accept objects of the same class or interface as a current class. Stack overflow for teams is a private secure spot for you and your coworkers to find and share information. The decorator design pattern falls under the category of structural design pattern.

Decorator pattern the decorator pattern provides a flexible alternative to sub classing for extending functionality dynamically. Decorator pattern is used to add new functionality to an existing object without changing its structure. The idea of the decorator pattern is to wrap an existing class add other functionality to it then expose the same interface to the outside world. In other words it wants to add new responsibilities to an individual instance of an object without adding those responsibilities to the class of objects.

Understanding decorator design pattern in c. Please read our previous article where we discussed the facade design pattern in c with examples. All other patterns and much more are available in our net design pattern framework 4 5. Reading your article make me understand it.

Decorator can be thought of as an alternative to inheritance. Ask question asked 3 years 7 months ago. 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 decorator is pretty standard in c code especially in code related to streams.

Decorator design pattern falls under structural pattern of gang of four gof design patterns in net. Hence decorator pattern provides an alternative way to inheritance for modifying the behavior of an object. Usage of the pattern in c. The decorator pattern allows to attach additional responsibilities to an object dynamically.

Being a c developer i was a bit confused with the syntax of java. Instead of creating a silly example of usage i decided to rely on one of the best example of implementation that is already available in the net framework. Net optimized code in c. Active 10 months ago.

As part of this article we are going to discuss the following pointers. Decorator design pattern in c with examples. You can find an example on our singleton pattern page. The decorator design pattern is quite popular in c due to the fact that it helps us dynamically add behaviors to the wrapped objects.

The decorator design pattern seeks to add new functionality to an existing object without changing that object s definition.
