Class ConcurrentEnumMap<K extends Enum<K>, V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.EnumMap<K,V>

tools.ConcurrentEnumMap<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

public final class ConcurrentEnumMap<K extends Enum<K>, V>
extends EnumMap<K,V>
implements Serializable

以讀寫鎖保護的執行緒安全 EnumMap，供多執行緒並行存取 Enum 鍵的映射。

繼承自 EnumMap，以 ReentrantReadWriteLock 覆寫全部公開存取方法：讀取操作（get、containsKey、size 等）取讀鎖， 寫入操作（put、remove、clear 等）取寫鎖，允許多個讀者並行、 但寫者獨佔。

本類別在 TWMS v149 的並行重構中取代了部分使用 HashMap 的狀態容器， 例如 buff 狀態與技能冷卻等以 Enum 為鍵的映射。
