public abstract class ModifiableObservableListBase<E> extends ObservableListBase<E>
Abstract class that serves as a base class for ObservableList implementations that are modifiable. To implement a modifiable ObservableList class, you just need to implement the following set of methods: and the notifications and built and fired automatically for you.

Example of a simple ObservableList delegating to another List would look like this: 


   public class ArrayObservableList<E> extends ModifiableObservableList<E> {

   private final List<E> delegate = new ArrayList<>();

   public E get(int index) {
       return delegate.get(index);
   }

   public int size() {
       return delegate.size();
   }

   protected void doAdd(int index, E element) {
       delegate.add(index, element);
   }

   protected E doSet(int index, E element) {
       return delegate.set(index, element);
   }

   protected E doRemove(int index) {
       return delegate.remove(index);
   }
