Examples of JsopWriter

org.apache.jackrabbit.mk.json.JsopWriter
A builder for Json and Json diff strings. It knows when a comma is needed. A comma is appended before '{', '[', a value, or a key; but only if the last appended token was '}', ']', or a value. There is no limit to the number of nesting levels.
