`Mediator`__
|
|
============
|
|
|
|
Purpose
|
|
-------
|
|
|
|
This pattern provides an easy to decouple many components working
|
|
together. It is a good alternative over Observer IF you have a "central
|
|
intelligence", like a controller (but not in the sense of the MVC).
|
|
|
|
All components (called Colleague) are only coupled to the
|
|
MediatorInterface and it is a good thing because in OOP, one good friend
|
|
is better than many. This is the key-feature of this pattern.
