Class CaseInsensitiveHashtable

java.lang.Object

java.util.Dictionary<K,V>

java.util.Hashtable

org.safs.text.CaseInsensitiveHashtable

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public class CaseInsensitiveHashtable
extends java.util.Hashtable

Overrides java.util.Hashtable methods to allow for case-insensitive String key matches. This also means that 2 string keys differing only by case will not exist. Normal Hashtable functionality prevails unless a call to affected methods does not find a match. In that event, if the key is a String we will attempt to locate an appropriate String key by ignoring the case of the key.
