NoOpVisitor

upickle.core.NoOpVisitor$
object NoOpVisitor extends Visitor[Unit, Unit]

NullFacade discards all JSON AST information.

This is the simplest possible facade. It could be useful for checking JSON for correctness (via parsing) without worrying about saving the data.

It will always return () on any successful parse, no matter the content.

Concrete methods

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

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

Value parameters

index

json source position at the start of the false being visited

Attributes

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

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

d

the input number
