Class RingBufferAppender

java.lang.Object
ch.qos.logback.core.spi.ContextAwareBase
ch.qos.logback.core.AppenderBase<ch.qos.logback.classic.spi.ILoggingEvent>
server.gui.RingBufferAppender
All Implemented Interfaces:
ch.qos.logback.core.Appender<ch.qos.logback.classic.spi.ILoggingEvent>, ch.qos.logback.core.spi.ContextAware, ch.qos.logback.core.spi.FilterAttachable<ch.qos.logback.classic.spi.ILoggingEvent>, ch.qos.logback.core.spi.LifeCycle
public final class RingBufferAppender extends ch.qos.logback.core.AppenderBase<ch.qos.logback.classic.spi.ILoggingEvent>
自訂 logback Appender：把 WARN／ERROR 等級的日誌事件擷取進 ServerEventLog 的記憶體環狀緩衝，供 GUI 管理控制台「最近事件」面板讀取。

於 src/logback.xml 以 <appender class="server.gui.RingBufferAppender"> 宣告並掛在 root 下，另以 ThresholdFilter level=WARN 僅放行 WARN 以上。 此 Appender 不觸碰資料庫、不阻塞 logging 執行緒（僅一次 synchronized 入列）。

分類推導：訊息或 logger 來自封包處理（MapleServerHandler / 含「數據包」）→ 「封包異常」；其餘 ERROR → 「系統錯誤」；WARN → 「警告」。反作弊偵測不經 SLF4J， 由 CheatTracker 直接寫入 ServerEventLog.anticheat(String)，不在此處。
