Class CompactCIHashMap<K,V>

java.lang.Object

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

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

All Implemented Interfaces:

Map<K,V>

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

Useful Map that does not care about the case-sensitivity of keys when the key value is a String. Other key types can be used. String keys will be treated case insensitively, yet key case will be retained. Non-string keys will work as they normally would.

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