NBT indexer for reading large NBT data efficiently

One of the annoying properties of NBT is that the entire thing has to be parsed in order to know how long it is, because a length prefix usually isn t included where it s used. It s also very annoying ...

Store binary-encoded simple tags inside `CompoundTag` and `ListTag` instead of useless boxing objects

User code rarely interacts with the likes of IntTag directly. It s also horribly inefficient to box integers this way. In addition, extra objects means extra work for the GC. All simple tags (byte, short, ...

Add a serializer flag to force ordering of TAG_Compound keys

It may be desirable to keep an encoded binary cache of an NBT tree, to be able to do fast bytewise comparison (such comparisons are vectorizable, and as such, considerably faster than making many thousands ...

Better handling of duplicate CompoundTag keys

Currently, a duplicate key appearing anywhere in some NBT data tree will cause the entire tree to be undecodable using this library. This is severely problematic for legacy PM worlds, because the entire ...

Make Tag->getTypeName() public
