Class JsonThing

java.lang.Object

com.dropbox.client2.jsonextract.JsonThing

public final class JsonThing
extends java.lang.Object

(Internal class for extracting JSON.)

A utility class to let you extract your required structure out of an org.json.simple object.

As you descend into the object and pull our your data, these classes keep track of where you are, so if there's an error in the JSON value, you'll get a "path" string describing exactly where the problem is.
