This method should not be used by plugins, it's used to add tracked inventories for InventoryActions involving inventories.

Parameters:

inventory - to add

matchItems

 List<org.cloudburstmc.api.item.ItemStack> haveItems)

sendInventories

protected void sendInventories()

squashDuplicateSlotChanges

protected boolean squashDuplicateSlotChanges()

Iterates over SlotChangeActions in this transaction and compacts any which refer to the same inventorySlot in the same inventory so they can be correctly handled.

Under normal circumstances, the same inventorySlot would never be changed more than once in a single transaction. However, due to the way things like the crafting grid are "implemented" in MCPE 1.2 (a.k.a. hacked-in), we may get multiple inventorySlot changes referring to the same inventorySlot in a single transaction. These multiples are not even guaranteed to be in the correct order (inventorySlot splitting in the crafting grid for example, causes the actions to be sent in the wrong order), so this method also tries to chain them into order.

Returns:

successful

canExecute

public boolean canExecute()

callExecuteEvent

protected boolean callExecuteEvent()

execute

public boolean execute()

hasExecuted

public boolean hasExecuted()
