java.lang.Objectjava.util.AbstractMap<K,V>
org.apache.commons.collections15.map.AbstractHashedMap<String,V>
org.apache.commons.collections15.map.CaseInsensitiveMap<V>
public class CaseInsensitiveMap<V>
A case-insensitive Map.
newKey.toLower()
to the lowercase values in the current KeySet.
Null keys are supported.
The keySet() method returns all lowercase keys, or nulls.
Example:
Map map = new CaseInsensitiveMap();
map.put("One", "One");
map.put("Two", "Two");
map.put(null, "Three");
map.put("one", "Four");
creates a CaseInsensitiveMap with three entries.map.get(null) returns "Three" and map.get("ONE")
returns "Four". The Set returned by keySet()
equals {"one", "two", null}.
