getRemainingStacks

public <C extends Inventory,
T extends Recipe<C>>
DefaultedList<ItemStack> getRemainingStacks(RecipeType<T> type,

world - the input world

Returns:

the remainder of a recipe of the given type that match the given inventory and world, or a shallow copy of the inventory

keys

public Stream<Identifier> keys()

Returns a stream of IDs of recipes in this manager.

The returned stream does not update after setRecipes(Iterable) call.

Returns:

a stream of IDs of recipes in this manager

deserialize

public static Recipe<?> deserialize(Identifier id,
 JsonObject json)

Reads a recipe from a JSON object.

Parameters:

id - the recipe's ID

json - the recipe JSON

Returns:

the read recipe

Throws:

JsonParseException - if the recipe JSON is invalid

• RecipeSerializer.read(net.minecraft.util.Identifier, com.google.gson.JsonObject)

Implementation Note:

Even though a recipe's serializer is stored in a type field in the JSON format and referred so in this method, its registry has key minecraft:root/minecraft:recipe_serializer and is thus named.
