public class OrderedMultiSelectionModel<T>
extends MultiSelectionModel<T>

A simple selection model that allows multiple items to be selected and retains order of selection. Selecting the same item multiple times does not change the order (item won't be moved to the end of selection). OrderedMultiSelectionModel uses LinkedHashMaps, which may increase the size of your compiled output if you do not use LinkedHashMaps elsewhere in your application.
