final class ByteArrayParser[J] extends Parser[J] with ByteBasedParser[J]
Basic ByteBuffer parser.
This assumes that the provided ByteBuffer is ready to be read. The user is responsible for any necessary flipping/resetting of the ByteBuffer before parsing.
The parser makes absolute calls to the ByteBuffer, which will not update its own mutable position fields.

The reset() method is used to signal that we're working from the given position, and any previous data can be released. Some parsers (e.g. StringParser) will ignore release, while others (e.g. PathParser) will need to use this information to release and allocate different areas.

Parse the JSON document into a single JSON value.
The parser considers documents like '333', 'true', and '"foo"' to be valid, as well as more traditional documents like [1,2,3,4,5]. However, multiple top-level objects are not allowed.

parseNum(i: Int, ctxt: ObjArrVisitor[Any, J], facade: Visitor[_, J]): Int
Parse the given number, and add it to the given context.
Parse the given number, and add it to the given context.
We don't actually instantiate a number here, but rather pass the string of for future use. Facades can choose to be lazy and just store the string. This ends up being way faster and has the nice side-effect that we know exactly how the user represented the number.

parseNumSlow(i: Int, facade: Visitor[_, J]): (J, Int)
Parse the given number, and add it to the given context.
Parse the given number, and add it to the given context.
This method is a bit slower than parseNum() because it has to be sure it doesn't run off the end of the input.
Normally (when operating in rparse in the context of an outer array or object) we don't need to worry about this and can just grab characters, because if we run out of characters that would indicate bad input. This is for cases where the number could possibly be followed by a valid EOF.
This method has all the same caveats as the previous method.

See if the string has any escape sequences. If not, return the end of the string. If so, bail out and return -1.

rparse(state: Int, j: Int, stack: List[ObjArrVisitor[_, J]]): (J, Int)
Tail-recursive parsing method to do the bulk of JSON parsing.
Tail-recursive parsing method to do the bulk of JSON parsing.
This single method manages parser states, data, etc. Except for parsing non-recursive values (like strings, numbers, and constants) all important work happens in this loop (or in methods it calls, like reset()).
Currently the code is optimized to make use of switch statements. Future work should consider whether this is better or worse than manually constructed if/else statements or something else. Also, it may be possible to reorder some cases for speed improvements.
