Class MTSCart

java.lang.Object

server.MTSCart

All Implemented Interfaces:

Serializable

public class MTSCart
extends Object
implements Serializable

單一角色在楓之谷交易所（MTS）的購物車與轉移背包狀態。

本類別封裝每位角色於 MTS 中的本地會話資料，包含：

• transfer：MTS 轉移背包（由 ItemLoader.MTS_TRANSFER 從資料庫載入），存放已購買或下架待領取的道具。
• cart（購物車）：已加入觀察清單的上架商品 packageId 集合，存於 mts_cart 資料庫表。
• notYetSold：玩家自己尚未售出的上架商品 packageId 清單（不持久，僅記憶體）。
• owedNX：因購買完成而應回補給賣家的楓葉點數餘額。

由 MTSStorage 統一管理所有玩家的 MTSCart 實例； 瀏覽頁面邏輯（tab/type/page 切換、getCurrentViewPage() 分頁）由本類別維護， 實際商品資料仍從 MTSStorage 讀取。 實作 Serializable 以支援跨伺服器移轉。
