upickle.core.SimpleVisitor
trait SimpleVisitor[-T, +V] extends Visitor[T, V]

Abstract methods

def expectedMsg: String

Concrete methods

def visitArray(length: Int, index: Int): ArrVisitor[T, V]

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 visitBinary(bytes: Array[Byte], offset: Int, len: Int, index: Int): V
def visitChar(s: Char, index: Int): V
def visitExt(tag: Byte, bytes: Array[Byte], offset: Int, len: Int, index: Int): V
def visitFalse(index: Int): V

Value parameters

index

json source position at the start of the false being visited

Attributes

def visitFloat32(d: Float, index: Int): V
def visitFloat64(d: Double, index: Int): V

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).

Delegates to visitFloat64StringParts if not overriden

Value parameters
