public class JsonOutput
extends java.lang.Object
Class responsible for the actual String serialization of the possible values of a JSON structure. This class can also be used as a category, so as to add toJson() methods to various types.

This class does not provide the ability to customize the resulting output. A JsonGenerator can be used if the ability to alter the resulting output is required.
