MTSStorage

java.lang.Object

server.MTSStorage

public class MTSStorage extends Object

楓之谷交易所（MTS）的全域在記憶體儲存層，管理所有上架商品與玩家購物車的讀寫與定期同步。

本類別為全域單例（getInstance()），在 CashShopServer 啟動時由 load() 初始化。核心資料結構：

buyNow（packageId → MTSStorage.MTSItemInfo）：全伺服器立即購買清單，以 ReentrantReadWriteLock 保護。
idToCart（characterId → MTSCart）：各玩家購物車快取，以獨立的 cart_mutex 保護。

主要操作：addToBuyNow(MTSCart, Item, int, int, String, long) 上架商品、removeFromBuyNow(int, int, boolean) 購買/下架、 getCart(int) 取得或建立玩家購物車、saveBuyNow(boolean) 批次持久化（含清除到期商品並退回轉移背包）、checkExpirations() 每小時觸發一次儲存。封包組裝委由 tools.packet.MTSCSPacket；稅金計算使用 constants.ServerConstants 的 MTS_BASE 與 MTS_TAX。靜態內部類 MTSStorage.MTSItemInfo 保存單筆上架商品（道具、售價、賣家、到期時間）。
