Class CaseInsensitiveMap<T>

java.lang.Object

org.conqat.lib.commons.collections.CaseInsensitiveMap<T>

All Implemented Interfaces:

java.util.Map<java.lang.String,T>

public class CaseInsensitiveMap<T>
extends java.lang.Object
implements java.util.Map<java.lang.String,T>

Map implementation that supports case-insensitive String keys. Note that while the method signatures of the Map interface allows arbitrary Objects as keys, this class will throw IllegalArgumentExceptions when using non String keys (null keys are supported). Also note that {link keySet()} will return lower cased keys.
