ByteParser

abstract class ByteParser[J] extends BufferingByteParser

A specialized JSON parse that can parse Bytes (Chars or Bytes), sending method calls to the given upickle.core.Visitor.

Generally has a lot of tricks for performance: e.g. having duplicate implementations for nested v.s. top-level parsing, using an ByteBuilder to construct the CharSequences that visitString requires, etc.

  30. final def parse(facade: Visitor[_, J]): J

    Parse the JSON document into a single JSON value.

    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.

  31. final def parseFalse(i: Int, facade: Visitor[_, J]): J

    Parse the JSON constant "false".

    Parse the JSON constant "false".

    Note that this method assumes that the first character has already been checked.

  32. final def parseNested(state: Int, i: Int, stackHead: ObjArrVisitor[_, J], stackTail: 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.

  34. final def 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.

    protected[this]
  35. final def parseNumTopLevel(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.
