org.aoju.bus.core.map

Class CaseInsensitiveMap<K,V>

java.lang.Object

org.aoju.bus.core.map.MapWrapper<K,V>

org.aoju.bus.core.map.CustomKeyMap<K,V>

org.aoju.bus.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

public class CaseInsensitiveMap<K,V>
extends CustomKeyMap<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:

JDK 1.8+
