Examples of org.richfaces.json.JSONObject

org.richfaces.json.JSONObject
A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get and opt methods for accessing the values by name, and put methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, String, or the JSONObject.NULL object. A JSONObject constructor can be used to convert an external form JSON text into an internal form whose values can be retrieved with the get and opt methods, or to convert values into a JSON text using the put and toString methods. A get method returns a value if one can be found, and throws an exception if one cannot be found. An opt method returns a default value instead of throwing an exception, and so is useful for obtaining optional values.
The generic get() and opt() methods return an object, which you can cast or query for type. There are also typed get and opt methods that do type checking and type coersion for you.
The put methods adds values to an object. For example,
```
 myString = new JSONObject().put("JSON", "Hello, World!").toString(); 
```
produces the string {"JSON": "Hello, World"}.
The texts produced by the toString methods strictly conform to the JSON sysntax rules. The constructors are more forgiving in the texts they will accept:
- An extra , (comma) may appear just before the closing brace.
- Strings may be quoted with ' (single quote).
- Strings do not need to be quoted at all if they do not begin with a quote or single quote, and if they do not contain leading or trailing spaces, and if they do not contain any of these characters: { } [ ] / \ : , = ; # and if they do not look like numbers and if they are not the reserved words true, false, or null.
- Keys can be followed by = or => as well as by :.
- Values can be followed by ; (semicolon) as well as by , (comma).
- Numbers may have the 0- (octal) or 0x- (hex) prefix.
- Comments written in the slashshlash, slashstar, and hash conventions will be ignored.
