Decorator

Attach additional responsibilities to an object dynamically. Decorators provide a flexible alternative to subclassing for extending functionality. The pattern has structural purpose and applies to objects.

When to use

to add responsibilities to individual objects dynamically and transparently, that is, without affecting other objects
for responsibilities that can be withdrawn
when extension by subclassing is impractical
