## 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.
## Class diagram
![alt text](./etc/delegation.png "Delegate")
## 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.
