This is the third post in a series of post on Design patterns. Presently we are going through the structural patterns. I will be writing about the bridge pattern today.

You can read about the other patterns from the following links

1. Decorator Pattern
2. Proxy Pattern

The Bridge pattern deals with removing the tight coupling of implementation of a class from its abstraction.  It helps the code to have backward functionality in the sense that, if there is a new version of implementation available, then the older version should not break i.e the older consumer of the code should not break.

This is the second post in a series of post on Design patterns. Presently we are going through the structural patterns. In my previous post I had discussed about the Decorator Pattern. I will be writing about the proxy pattern today.

Proxy patterns is all about creating small objects which in turn are used in creating and accessing more complex objects.

Yes there are a lot of posting on design patterns, and you might ask why another of these post on design patterns. I am doing this post so that I can document the design patterns for myself for later use.

There are 23 design patterns as observed by the Gang Of Four (Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides). And they are categorized basically into 3 segments viz. Structural, Creational and Behavioral patterns. I will take these in order.

To begin with I will start with the Decorator pattern.
