    Class ObservableObjectAbstract

    A base class for objects that notify subscribers when their properties change.

    • Do not confuse with Observable<T> from rxjs library. The latter represents a asynchronous stream of data.
    • Derived classes should call _notifyPropertyChanged whenever a property value changes.
    class Person extends ObservableObject {
      private _name: string = "";
      
      public get name(): string { return this._name; }
      public set name(value: string) {
        if (this._name !== value) {
          this._name = value;
          this._notifyPropertyChanged("name");
        }
      }
    }
