OK, so let's get this out of the way, there's some actual changes mixed in here too. I'm really sorry: - Turtles can now not be renamed with unnamed item tags (previously it would clear the name, this seemed a little unideal). - commands.getBlock(s)Data will also include NBT. Now, onto the horror story which is these inspection changes: - Make a lot of methods static - Typo fixes - Make utility classes final + private constructor - Lots of reformatting (ifs -> ternary, invert control flow, etc...) - ??? - Profit! I'm so going to regret this - can pretty much guarantee this is going to break something.

/**
|
|
* An alternative closeable implementation that will free up resources in the filesystem.
|
|
*
|
|
* The {@link FileSystem} maps weak references of this to its underlying object. If the wrapper has been disposed of
|
|
* (say, the Lua object referencing it has gone), then the wrapped object will be closed by the filesystem.
|
|
*
|
|
* Closing this will stop the filesystem tracking it, reducing the current descriptor count.
|
|
*
|
|
* In an ideal world, we'd just wrap the closeable. However, as we do some {@code instanceof} checks
|
|
* on the stream, it's not really possible as it'd require numerous instances.
|
|
*
|
|
* @param <T> The type of writer or channel to wrap.
