public class NbtList extends AbstractNbtList<NbtElement>
Represents a mutable NBT list. Its type is 0x9.

An NBT list holds values of the same NBT type. The NBT type of an NBT list is determined once its first element is inserted; empty NBT lists return NbtElement.END_TYPE as their held NBT type.

To get values from this list, use methods with type names, such as getInt(int). Where applicable, these methods return Java types (e.g. int, long[]) instead of NbtElement subclasses. If type mismatch occurs or the index is out of bounds, it returns the default value for that type instead of throwing or returning null.

Unlike NbtCompound, there is no Java type-based adder, and numeric value getters will not try to cast the values.
