Method Detail

getTopInventory

public abstract Inventory getTopInventory()

Get the upper inventory involved in this transaction.

Returns:

the inventory

getBottomInventory

public abstract Inventory getBottomInventory()

Get the lower inventory involved in this transaction.

Returns:

the inventory

getPlayer

public abstract HumanEntity getPlayer()

Get the player viewing.

Returns:

the player

getType

public abstract InventoryType getType()

Determine the type of inventory involved in the transaction. This indicates the window style being shown. It will never return PLAYER, since that is common to all windows.

Returns:

the inventory type

setItem

public void setItem(int slot,
           ItemStack item)

Sets one item in this inventory view by its raw slot ID.

Note: If slot ID -999 is chosen, it may be expected that the item is dropped on the ground. This is not required behaviour, however.

Parameters:

slot - The ID as returned by InventoryClickEvent.getRawSlot()

item - The new item to put in the slot, or null to clear it.

getItem

public ItemStack getItem(int slot)

Gets one item in this inventory view by its raw slot ID.

Parameters:

slot - The ID as returned by InventoryClickEvent.getRawSlot()

Returns:

The item currently in the slot.

setCursor

public final void setCursor(ItemStack item)

Sets the item on the cursor of one of the viewing players.

Parameters:

item - The item to put on the cursor, or null to remove the item on their cursor.

getCursor

public final ItemStack getCursor()

Get the item on the cursor of one of the viewing players.

Returns:

The item on the player's cursor, or null if they aren't holding one.

convertSlot

public final int convertSlot(int rawSlot)

Converts a raw slot ID into its local slot ID into whichever of the two inventories the slot points to.

If the raw slot refers to the upper inventory, it will be returned unchanged and thus be suitable for getTopInventory().getItem(); if it refers to the lower inventory, the output will differ from the input and be suitable for getBottomInventory().getItem().

Parameters:

rawSlot - The raw slot ID.

Returns:

The converted slot ID.

close

public final void close()

Closes the inventory view.

countSlots

public final int countSlots()

Check the total number of slots in this view, combining the upper and lower inventories.

Note though that it's possible for this to be greater than the sum of the two inventories if for example some slots are not being used.

Returns:

The total size

setProperty

public final boolean setProperty(InventoryView.Property prop,
                  int value)

Sets an extra property of this inventory if supported by that inventory, for example the state of a progress bar.

Parameters:

prop - the window property to update

value - the new value for the window property

Returns:

true if the property was updated successfully, false if the property is not supported by that inventory

getTitle

public final String getTitle()

Get the title of this inventory window.

Returns:

The title.
