Package com.cedarsoftware.util

Class CompactLinkedMap<K,V>

java.lang.Object

com.cedarsoftware.util.CompactMap<K,V>

com.cedarsoftware.util.CompactLinkedMap<K,V>

All Implemented Interfaces:

Map<K,V>

public class CompactLinkedMap<K,V>
extends CompactMap<K,V>

This Map uses very little memory (See CompactMap). When the Map has more than 'compactSize()' elements in it, the 'delegate' Map is a LinkedHashMap.
