Observable

open class Observable<T> : ObservableIfc<T>

The Java observer/observable pattern has a number of flaws. This class provides a base implementation of the observer/observable pattern that mitigates those flaws. This allows observers to be added and called in the order added to the component. The basic usage of this class is to have a class have an instance of Observable while implementing the ObservableIfc. The notifyObservers() method can be used to notify attached observers whenever necessary.
