Method Detail

getSize

int getSize()
Returns the size of the inventory

Returns:
The size of the inventory

getMaxStackSize

int getMaxStackSize()
Returns the maximum stack size for an ItemStack in this inventory.

Returns:
The maximum size for an ItemStack in this inventory.

setMaxStackSize

void setMaxStackSize(int size)
This method allows you to change the maximum stack size for an inventory.

Caveats:

Parameters:
size - The new maximum stack size for items in this inventory.

getName

String getName()
Returns the name of the inventory

Returns:
The String with the name of the inventory

getItem

ItemStack getItem(int index)
Returns the ItemStack found in the slot at the given index

Parameters:
index - The index of the Slot's ItemStack to return
Returns:
The ItemStack in the slot

setItem

void setItem(int index,
             ItemStack item)
Stores the ItemStack at the given index of the inventory.

Parameters:
index - The index where to put the ItemStack
item - The ItemStack to set

addItem

HashMap<Integer,ItemStack> addItem(ItemStack... items)
                                   throws IllegalArgumentException
Stores the given ItemStacks in the inventory. This will try to fill existing stacks and empty slots as well as it can.

The returned HashMap contains what it couldn't store, where the key is the index of the parameter, and the value is the ItemStack at that index of the varargs parameter. If all items are stored, it will return an empty HashMap.

If you pass in ItemStacks which exceed the maximum stack size for the Material, first they will be added to partial stacks where Material.getMaxStackSize() is not exceeded, up to Material.getMaxStackSize(). When there are no partial stacks left stacks will be split on Inventory.getMaxStackSize() allowing you to exceed the maximum stack size for that material.

Parameters:
items - The ItemStacks to add
Returns:
A HashMap containing items that didn't fit.
Throws:
IllegalArgumentException - if items or any element in it is null

removeItem

HashMap<Integer,ItemStack> removeItem(ItemStack... items)
                                      throws IllegalArgumentException
Removes the given ItemStacks from the inventory.

It will try to remove 'as much as possible' from the types and amounts you give as arguments.

The returned HashMap contains what it couldn't remove, where the key is the index of the parameter, and the value is the ItemStack at that index of the varargs parameter. If all the given ItemStacks are removed, it will return an empty HashMap.

Parameters:
items - The ItemStacks to remove
Returns:
A HashMap containing items that couldn't be removed.
Throws:
IllegalArgumentException - if items is null

getContents

ItemStack[] getContents()
Returns all ItemStacks from the inventory

Returns:
An array of ItemStacks from the inventory.

setContents

void setContents(ItemStack[] items)
                 throws IllegalArgumentException
Completely replaces the inventory's contents. Removes all existing contents and replaces it with the ItemStacks given in the array.

Parameters:
items - A complete replacement for the contents; the length must be less than or equal to getSize().
