Package net.minecraft.item

Class BlockPredicatesChecker

java.lang.Object

net.minecraft.item.BlockPredicatesChecker

public class BlockPredicatesChecker
extends Object

Checks if a block predicate stored inside ItemStack's NBT matches the block in a world. The predicate must be stored inside the key sub NBT of the item stack.

The result is cached to reduce cost for successive lookups on the same block.

API Note:

This is used to implement checks for restrictions specified using CanPlaceOn or CanDestroy.
