Interface FixedItemInv.CopyingFixedItemInv

All Superinterfaces:

AbstractItemInvView, Convertible, FixedItemInv, FixedItemInvView

All Known Implementing Classes:

CombinedFixedItemInv.OfCopying, DelegatingFixedItemInv.OfCopying, FullFixedItemInv, MappedFixedItemInv.OfCopying, SimpleFixedItemInv, SimpleLimitedFixedItemInv.OfCopying, SubFixedItemInv.OfCopying

Enclosing interface:

FixedItemInv

public static interface FixedItemInv.CopyingFixedItemInv
extends FixedItemInv

The "complex" variant of FixedItemInv that always returns copies of the stack held. As such this allows per-slot listeners to be registered, and full filter usage (as no-one can modify this inventory in a way that is not permitted).

Method Summary

Modifier and Type	Method	Description
default ListenerToken	addListener(InvMarkDirtyListener listener, ListenerRemovalToken removalToken)	Adds the given listener to this inventory, such that InvMarkDirtyListener.onMarkDirty(AbstractItemInvView) will be called every time that any stored stack is changed (either from FixedItemInv.setInvStack(int, ItemStack, Simulation) or FixedItemInv.ModifiableFixedItemInv.markDirty()).
default ListenerToken	addListener(ItemInvSlotChangeListener listener, ListenerRemovalToken removalToken)	Adds the given listener to this inventory, such that the ItemInvSlotChangeListener.onChange(FixedItemInvView, int, ItemStack, ItemStack) will be called every time that this inventory changes.

Method Details

getInvStack

default net.minecraft.item.ItemStack getInvStack(int slot)

Specified by:

getInvStack in interface FixedItemInv

Specified by:

getInvStack in interface FixedItemInvView

Parameters:

slot - The slot index. Must be a value between 0 (inclusive) and FixedItemInvView.getSlotCount() (exclusive) to be valid. (Like in arrays, lists, etc).

Returns:

a copy of the ItemStack held in this inventory.

getUnmodifiableInvStack

net.minecraft.item.ItemStack getUnmodifiableInvStack(int slot)

Returns:

The ItemStack that is held by this inventory. Modifying the returned ItemStack in any way will (most likely - depending on the implementation) throw an exception (at some point).

getSlot

default SingleCopyingItemSlot getSlot(int slot)

Specified by:

getSlot in interface FixedItemInv

Specified by:

getSlot in interface FixedItemInvView

Returns:

A view of a single slot in this inventory.

addListener

default ListenerToken addListener(InvMarkDirtyListener listener,
 ListenerRemovalToken removalToken)

Description copied from interface: AbstractItemInvView

Adds the given listener to this inventory, such that InvMarkDirtyListener.onMarkDirty(AbstractItemInvView) will be called every time that any stored stack is changed (either from FixedItemInv.setInvStack(int, ItemStack, Simulation) or FixedItemInv.ModifiableFixedItemInv.markDirty()).

If the listener is registered (and thus this returns null) then it implies that AbstractItemInvView.getChangeValue() will change every time that the given listener is invoked, always just-before it is invoked.

The default implementation refuses to accept any listeners, but implementations are highly encouraged to override this if they are able to!

Specified by:

addListener in interface AbstractItemInvView

removalToken - A token that will be called whenever the given listener is removed from this inventory (or if this inventory itself is unloaded or otherwise invalidated).

Returns:

A token that represents the listener, or null if the listener could not be added.

addListener

default ListenerToken addListener(ItemInvSlotChangeListener listener,
 ListenerRemovalToken removalToken)

Adds the given listener to this inventory, such that the ItemInvSlotChangeListener.onChange(FixedItemInvView, int, ItemStack, ItemStack) will be called every time that this inventory changes. However if this inventory doesn't support listeners then this will return a null token.

The default implementation refuses to accept any listeners, but implementations are highly encouraged to override this if they are able to!

Parameters:

removalToken - A token that will be called whenever the given listener is removed from this inventory (or if this inventory itself is unloaded or otherwise invalidated).

Returns:

A token that represents the listener, or null if the listener could not be added.
