Class CaseInsensitiveMap<K,V>

java.lang.Object

cn.hutool.core.map.MapWrapper<K,V>

cn.hutool.core.map.TransMap<K,V>

cn.hutool.core.map.CustomKeyMap<K,V>

cn.hutool.core.map.FuncKeyMap<K,V>

cn.hutool.core.map.CaseInsensitiveMap<K,V>

Type Parameters:

K - 键类型

V - 值类型

All Implemented Interfaces:

Serializable, Cloneable, Iterable<Map.Entry<K,V>>, Map<K,V>

Direct Known Subclasses:

CaseInsensitiveLinkedMap, CaseInsensitiveTreeMap

public class CaseInsensitiveMap<K,V>
extends FuncKeyMap<K,V>

忽略大小写的Map
对KEY忽略大小写，get("Value")和get("value")获得的值相同，put进入的值也会被覆盖

Since:

3.0.2
