If you have ever used Java, you may have run across the java.util.Observable
|
|
class and the java.util.Observer interface. Using them, you can decouple an
|
|
object from the one or more objects that wish to be notified whenever
|
|
particular events occur. Class::Observable allows you to mimic this action.
