Class SimpleInventory

java.lang.Object
net.minecraft.inventory.SimpleInventory
All Implemented Interfaces:
Inventory, RecipeInputProvider, Clearable
Direct Known Subclasses:
ComposterBlock.ComposterInventory, ComposterBlock.DummyInventory, ComposterBlock.FullComposterInventory, EnderChestInventory

public class SimpleInventory extends Object implements Inventory, RecipeInputProvider
A generic implementation of Inventory. This is used in a number of places, mostly:
  • To store the input of a ScreenHandler while it is open. The inventory is stored as a field, and the screen handler will have a slot backed by that inventory.
  • When defining the clientside constructor for a ScreenHandler subclass. The contents of the inventory will then be automatically synced from the serverside screen handler, which queries the original inventory.
  • For entities and block entities which do not interact with hoppers and therefore do not need to implement Inventory themselves.

Changes to the inventory can be listened to either by subclassing this and overriding markDirty(), or by using addListener(net.minecraft.inventory.InventoryChangedListener).
