Encode an object into JSON text and write it to out.

If this object is a Map or a List, and it's also a JSONStreamAware or a JSONAware, JSONStreamAware or JSONAware will be considered firstly.

DO NOT call this method from writeJSONString(Writer) of a class that implements both JSONStreamAware and (Map or List) with "this" as the first parameter, use JSONObject.writeJSONString(Map, Writer) or JSONArray.writeJSONString(List, Writer) instead.

Parameters:

value - The JSON Object

Parameters:
