Class ListHashMap<K,V>

All Implemented Interfaces:

public class ListHashMap<K,V> extends Object implements Map<K,V>
Represents a 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.

This class is not thread-safe!
