- Type Parameters:
V
- Type of values placed in this Map.
public class CaseInsensitiveKeyMap<V> extends AbstractMap<String,V>
A Map implementation that uses case-insensitive (usingLocale.ENGLISH
) strings as keys.Keys must be instances of
String
. Note that this means thatnull
keys are not permitted.This implementation is not thread-safe.

putAll
public void putAll(Map<? extends String,? extends V> m)
Use this method with caution. If the input Map contains duplicate keys when the keys are compared in a case insensitive manner then some values will be lost when inserting via this method.
