ChangeLog
Version 1.1 (2009/01/23)
* Supports stoppable SAX-like content handler for streaming of JSON text
* Added JSONStreamAware to support streaming JSON text
* Added ContainerFactory to support creating arbitrary Map and List as JSON object and JSON array container during decoding
* Supports any Map and List as JSON object and JSON array container during encoding
* Added interface JSONAware
* Added ParseException to get detail error report while parsing
* Added escaping for Unicode characters that cause problems for browser JS eval
Version 1.02 (2009/01/10)
* Updated json.lex to improve performance of the lexer
* Removed Rope.java and related junit test

Simple Java toolkit for JSON (JSON.simple)
==========================================
http://www.JSON.org/java/json_simple.zip
1.Why the Simple Java toolkit (also named as JSON.simple) for JSON?
When I use JSON as the data exchange format between the AJAX client and JSP
for the first time, what worry me mostly is how to encode Java strings and
numbers correctly in the server side so the AJAX client will receive a well
formed JSON data. When I looked into the 'JSON in Java' directory in JSON
website,I found that wrappers to JSONObject and JSONArray can be simpler,
due to the simplicity of JSON itself. So I wrote the JSON.simple package.
2.Is it simple,really?
I think so. Take an example:
import org.json.simple.JSONObject;
JSONObject obj=new JSONObject();
obj.put("name","foo");
obj.put("num",new Integer(100));
obj.put("balance",new Double(1000.21));
obj.put("is_vip",new Boolean(true));
obj.put("nickname",null);
System.out.print(obj);
Result:
{"nickname":null,"num":100,"balance":1000.21,"is_vip":true,"name":"foo"}
The JSONObject.toString() will escape controls and specials correctly.
3.How to use JSON.simple in JSP?
Take an example in JSP:
<%@page contentType="text/html; charset=UTF-8"%>
<%@page import="org.json.simple.JSONObject"%>
<%
JSONObject obj=new JSONObject();
obj.put("name","foo");
obj.put("num",new Integer(100));
obj.put("balance",new Double(1000.21));
obj.put("is_vip",new Boolean(true));
obj.put("nickname",null);
out.print(obj);
out.flush();
%>
So the AJAX client will get the responseText.
4.Some details about JSONObject?
JSONObject inherits java.util.HashMap,so it don't have to worry about the
mapping things between keys and values. Feel free to use the Map methods
like get(), put(), and remove() and others. JSONObject.toString() will
combine key value pairs to get the JSON data string. Values will be escaped
into JSON quote string format if it's an instance of java.lang.String. Other
type of instance like java.lang.Number,java.lang.Boolean,null,JSONObject and
JSONArray will NOT escape, just take their java.lang.String.valueOf() result.
null value will be the JSON 'null' in the result.
It's still correct if you put an instance of JSONObject or JSONArray into an
instance of JSONObject or JSONArray. Take the example about:
JSONObject obj2=new JSONObject();
obj2.put("phone","123456");
obj2.put("zip","7890");
obj.put("contact",obj2);
System.out.print(obj);
Result:
{"nickname":null,"num":100,"contact":{"phone":"123456","zip":"7890"},"balance":1000.21,"is_vip":true,"name":"foo"}
The method JSONObject.escape() is used to escape Java string into JSON quote
string. Controls and specials will be escaped correctly into \b,\f,\r,\n,\t,
\",\\,\/,\uhhhh.
5.Some detail about JSONArray?
org.json.simple.JSONArray inherits java.util.ArrayList. Feel free to use the
List methods like get(),add(),remove(),iterator() and so on. The rules of
JSONArray.toString() is similar to JSONObject.toString(). Here's the example:
import org.json.simple.JSONArray;
JSONArray array=new JSONArray();
array.add("hello");
array.add(new Integer(123));
array.add(new Boolean(false));
array.add(null);
array.add(new Double(123.45));
array.add(obj2);//see above
System.out.print(array);
Result:
["hello",123,false,null,123.45,{"phone":"123456","zip":"7890"}]
6.What is JSONValue for?
org.json.simple.JSONValue is use to parse JSON data into Java Object.
In JSON, the topmost entity is JSON value, not the JSON object. But
it's not necessary to wrap JSON string,boolean,number and null again,
for the Java has already had the according classes: java.lang.String,
java.lang.Boolean,java.lang.Number and null. The mapping is:
JSON Java
------------------------------------------------
string <=> java.lang.String
number <=> java.lang.Number
true|false <=> java.lang.Boolean
null <=> null
array <=> org.json.simple.JSONArray
object <=> org.json.simple.JSONObject
------------------------------------------------
JSONValue has only one kind of method, JSONValue.parse(), which receives
a java.io.Reader or java.lang.String. Return type of JSONValue.parse()
is according to the mapping above. If the input is incorrect in syntax or
there's exceptions during the parsing, I choose to return null, ignoring
the exception: I have no idea if it's a serious implementaion, but I think
it's convenient to the user.
Here's the example:
String s="[0,{\"1\":{\"2\":{\"3\":{\"4\":[5,{\"6\":7}]}}}}]";
Object obj=JSONValue.parse(s);
JSONArray array=(JSONArray)obj;
System.out.println(array.get(1));
JSONObject obj2=(JSONObject)array.get(1);
System.out.println(obj2.get("1"));
Result:
{"1":{"2":{"3":{"4":[5,{"6":7}]}}}}
{"2":{"3":{"4":[5,{"6":7}]}}}
