public class ListHashMap<K,V> extends Object implements Map<K,V>
Map that is optimized for a small number of
entries. For a number of entries up to listSize the entries
are stored in arrays. After listSize entries are exceeded
storage switches internally to a Map and converts back
to being array based when its size is less than or equal to listSize.
Null keys or values are not supported.
