/**
* Mediator Pattern
*
* Use a mediator object to encapsulate a series of object interactions so that each object does not need to explicitly reference each other, thus loosening the coupling, and the interaction between them can be changed independently
*/
abstract class Mediator
{
abstract public function send($message,$colleague);
}
abstract class Colleague
{
private $_mediator = null;
public function Colleague($mediator)
{
$this->_mediator = $mediator;
}
public function send($message)
{
$this->_mediator->send($message,$this);
}
abstract public function notify($message);
}
