Class CaseInsensitiveHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<K,V>

com.sun.identity.common.CaseInsensitiveHashMap<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public class CaseInsensitiveHashMap<K,V>
extends HashMap<K,V>

A case insensitive hash map with case preservation. If key is a String, a case insensitive hash code is used for hashing but original case of the key is preserved.
