Module json_values

Package jsonvalues

Class JsNothing

java.lang.Object

jsonvalues.JsNothing

All Implemented Interfaces:

JsValue

public final class JsNothing
extends Object
implements JsValue

It's a special JSON element that represents 'nothing'. Inserting nothing in a JSON leaves the json unchanged. The functions that return a JsValue, like Json.get(JsPath), return nothing when no element is found, what makes them total on the input path.
