由于InventoryClickEvent是通过修改物品栏 的实现类来触发的，所以并非所有与物品栏相关的方法都是安全的。

下面这些属于HumanEntity和 InventoryView的方法不应该被处理 InventoryClickEvent事件的 事件处理器调用

Assuming the EntityHuman associated with this event is an instance of a Player, manipulating the MaxStackSize or contents of an Inventory will require an Invocation of Player.updateInventory().

Modifications to slots that are modified by the results of this InventoryClickEvent can be overwritten. To change these slots, this event should be cancelled and all desired changes to the inventory applied. Alternatively, scheduling a task using BukkitScheduler.runTask(Plugin, Runnable), which would execute the task on the next tick, would work as well.
