ujson.Value
See theValue companion trait
object Value extends AstTransformer[Value]

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.

case class InvalidData(data: Value, msg: String) extends Exception

Thrown when uPickle tries to convert a JSON blob into a given data structure but fails because part the blob is invalid

Thrown when uPickle tries to convert a JSON blob into a given data structure but fails because part the blob is invalid

Value parameters

data

The section of the JSON blob that uPickle tried to convert. This could be the entire blob, or it could be some subtree.

Concrete methods

def transform[T](j: Value, f: Visitor[_, T]): T
def visitArray(length: Int, index: Int): ArrVisitor[Value, Value]

Value parameters

index

json source position at the start of the [ being visited

Attributes

Returns

a Visitor used for visiting the elements of the array

def visitFalse(index: Int): Value

Value parameters

index

json source position at the start of the false being visited

Attributes

override def visitFloat64(d: Double, index: Int): Value

Optional handler for raw double values; can be overriden for performance in cases where you're translating directly between numbers to avoid the overhead of stringifying and re-parsing your numbers (e.g. the WebJson transformer gets raw doubles from the underlying Json.parse).
