Decorator Design Pattern : As per the GOF definition, decorator Pattern states that we need to “Attach additional responsibilities to an object dynamically. Decorators provide A flexible alternative to sub classing for extending functionality.”

This pattern Falls under the category of Structural Design Pattern and is also known as Wrapper.

Implementation Guidelines : We need to use Decorator Design Pattern when
1. We need to add responsibilities to individual objects dynamically and transparently,
2. The extension by sub classing is impractical.
3. Class definition may be hidden or otherwise unavailable for sub classing.
