- case class Arr(value: ArrayBuffer[Value]) extends Value with Product with Serializable
- trait AstTransformer[I] extends Transformer[I] with JsVisitor[I, I]
- class BaseByteRenderer[T <: Output] extends JsVisitor[T, T]
A specialized JSON renderer that can render Bytes (Chars or Bytes) directly to a java.io.Writer or java.io.OutputStream
A specialized JSON renderer that can render Bytes (Chars or Bytes) directly to a java.io.Writer or java.io.OutputStream
Note that we use an internal
ByteBuilder
to buffer the output internally before sending it to out in batches. This lets us benefit from the high performance and minimal overhead ofByteBuilder
in the fast path of pushing characters, and avoid the synchronization/polymorphism overhead of out on the fast path. Most outs would also have performance benefits from receiving data in batches, rather than elem by elem. - class BaseCharRenderer[T <: Output] extends JsVisitor[T, T]

- final class ByteArrayParser[J] extends ByteParser[J]
Basic ByteBuffer parser.
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.

- 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.
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 theCharSequences
thatvisitString
requires, etc. - case class BytesRenderer(indent: Int = -1, escapeUnicode: Boolean = false) extends BaseByteRenderer[ByteArrayOutputStream] with Product with Serializable

- sealed trait IndexedValue extends AnyRef
A version of ujson.Value that keeps the index positions of the various AST nodes it is constructing.
A version of ujson.Value that keeps the index positions of the various AST nodes it is constructing. Usually not necessary, but sometimes useful if you want to work with an AST but still provide source-index error positions if something goes wrong
- final class InputStreamParser[J] extends ByteParser[J] with BufferingInputStreamParser
Parser that reads in bytes from an InputStream, buffering them in memory until a
reset
call discards them.Parser that reads in bytes from an InputStream, buffering them in memory until a
reset
call discards them.Mostly the same as ByteArrayParser, except using an UberBuffer rather than reading directly from an Array[Byte].
Generally not meant to be used directly, but via ujson.Readable.fromReadable
- trait JsVisitor[-T, +J] extends Visitor[T, J]
A Visitor specialized to work with JSON types.
A Visitor specialized to work with JSON types. Forwards the not-JSON-related methods to their JSON equivalents.

A very small, very simple JSON AST that uPickle uses as part of its serialization process.
A very small, very simple JSON AST that uPickle uses as part of its serialization process. A common standard between the Jawn AST (which we don't use so we don't pull in the bulk of Spire) and the Javascript JSON AST.
