public class MergeObservableList<T>
extends java.util.AbstractList<T>

An ObservableList that presents multiple lists and items as one contiguous source. Changes to any of the given lists will be reflected here. You cannot modify MergeObservableList itself other than adding and removing backing lists or items with insertItem(Object) and #insertList(ObservableList) respectively. This is a good case where you have multiple data sources, or a handful of fixed items mixed in with lists of data.
