public class Sortr
extends Object
implements Transform

Recursively sorts all maps within a JSON object into new sorted LinkedHashMaps so that serialized representations are deterministic. Useful for debugging and making test fixtures. Note this will make a copy of the input Map and List objects. The sort order is standard alphabetical ascending, with a special case for "~" prefixed keys to be bumped to the top.
