Also known as
Proxy Pattern
Intent
It is a technique where an object expresses certain behavior to the outside but in reality delegates responsibility for implementing that behaviour to an associated object.
Applicability
Use the Delegate pattern in order to achieve the following
- Reduce the coupling of methods to their class
- Components that behave identically, but realize that this situation can change in the future.
