Adapter Pattern, a directory of sites

This wiki page provides a directory of sites for Adapter Design Pattern that will help readers to know what each website contains, why should readers refer one website over another and a list of examples that readers can look up to understand the Adapter Pattern.

Introduction

Sometimes, objects just don't fit together as they should. A class may have changed, or an object turns out to be just too difficult to work with. At such times, adapter design pattern comes to the rescue. Adapter pattern lets you adapt what an object or class has to offer so that another object or class can make use of it. It also helps when classes can't work together because of incompatible interfaces.

Since we are huge fans of visual approach, lets understand the adapter pattern with the help of a diagram. Hold on! Before going in to the UML diagram ( which is kind of lets attractive, right? May be .. ) lets look at the figure below which is more appealing.

A real world example for the Adapter Pattern.

The above example helps readers quickly get across the intent of the pattern than the UML diagram shown below. Looking at the UML diagram now, can help the readers to learn about the precise relationships between the classes in adapter pattern and it makes a lot more sense!
