          extended by org.biojava.utils.SmallSet
All Implemented Interfaces:
Iterable, Collection, Set

public class SmallSet
extends AbstractSet

Lightweight implementation of Set which uses little memory to store a small number of items, at the expense of scalability. Not recomended for more than 20-30 items.

This implementation has the useful property that the iteration order is the same as the order in which the items are added.
