- jsonvalues.JsNothing
-
- All Implemented Interfaces:
JsValue
public final class JsNothing extends java.lang.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, likeJson.get(JsPath), return nothing when no element is found, what makes them total on the input path.
