Class StackCopySlot

java.lang.Object
net.minecraft.world.inventory.Slot
net.neoforged.neoforge.world.inventory.StackCopySlot
Direct Known Subclasses:
ItemHandlerCopySlot, ResourceHandlerSlot
public abstract class StackCopySlot extends Slot
Slot to handle immutable itemstack storages (Ex: ItemAccessItemHandler).

For an implementation for use with a ResourceHandler see ResourceHandlerSlot.

Vanilla MC code modifies the stack returned by getItem() directly, but it calls setChanged() when that happens, so we just cache the returned stack, and set it when setChanged() is called.
