getIndexForSlot

protected int getIndexForSlot(int slot)

getHandlerFromIndex

protected IItemHandlerModifiable getHandlerFromIndex(int index)

getSlotFromIndex

protected int getSlotFromIndex(int slot,
                               int index)

setStackInSlot

public void setStackInSlot(int slot,
                           ItemStack stack)

Description copied from interface: IItemHandlerModifiable

Overrides the stack in the given slot. This method is used by the standard Forge helper methods and classes. It is not intended for general use by other mods, and the handler may throw an error if it is called unexpectedly.

Specified by:

setStackInSlot in interface IItemHandlerModifiable

Parameters:

slot - Slot to modify

stack - ItemStack to set slot to (may be null)

getSlots

public int getSlots()

Description copied from interface: IItemHandler

Returns the number of slots available

Specified by:

getSlots in interface IItemHandler

Returns:

The number of slots available

getStackInSlot

public ItemStack getStackInSlot(int slot)

Description copied from interface: IItemHandler

Returns the ItemStack in a given slot. The result's stack size may be greater than the itemstacks max size. If the result is null, then the slot is empty. If the result is not null but the stack size is zero, then it represents an empty slot that will only accept* a specific itemstack.

IMPORTANT: This ItemStack MUST NOT be modified. This method is not for altering an inventories contents. Any implementers who are able to detect modification through this method should throw an exception.

SERIOUSLY: DO NOT MODIFY THE RETURNED ITEMSTACK

Specified by:

getStackInSlot in interface IItemHandler

Parameters:

slot - Slot to query

Returns:

ItemStack in given slot. May be null.

insertItem

public ItemStack insertItem(int slot,
                            ItemStack stack,
                            boolean simulate)

Description copied from interface: IItemHandler

Inserts an ItemStack into the given slot and return the remainder. The ItemStack should not be modified in this function! Note: This behaviour is subtly different from IFluidHandlers.fill()

Specified by:

insertItem in interface IItemHandler

Parameters:

slot - Slot to insert into.

stack - ItemStack to insert.

simulate - If true, the insertion is only simulated

Returns:

The remaining ItemStack that was not inserted (if the entire stack is accepted, then return null). May be the same as the input ItemStack if unchanged, otherwise a new ItemStack.

extractItem

public ItemStack extractItem(int slot,
                             int amount,
                             boolean simulate)

Description copied from interface: IItemHandler

Extracts an ItemStack from the given slot. The returned value must be null if nothing is extracted, otherwise it's stack size must not be greater than amount or the itemstacks getMaxStackSize().

Specified by:

extractItem in interface IItemHandler

Parameters:

slot - Slot to extract from.

amount - Amount to extract (may be greater than the current stacks max limit)

simulate - If true, the extraction is only simulated

Returns:

ItemStack extracted from the slot, must be null, if nothing can be extracted
