Type Parameters:
E - the type of the elements contained in the List
All Implemented Interfaces:
Iterable<E>, Collection<E>, List<E>, SequencedCollection<E>, Observable, ObservableList<E>
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);
  }
