JSONTokener Class

Definition

Parses a JSON (RFC 4627) encoded string into the corresponding object.

Remarks

Parses a JSON (RFC 4627) encoded string into the corresponding object. Most clients of this class will use only need the #JSONTokener(String) constructor and #nextValue method. Example usage:

String json = "{"
                    + "  \"query\": \"Pizza\", "
                    + "  \"locations\": [ 94043, 90210 ] "
                    + "}";

            JSONObject object = (JSONObject) new JSONTokener(json).nextValue();
            String query = object.getString("query");
            JSONArray locations = object.getJSONArray("locations");

For best interoperability and performance use JSON that complies with RFC 4627, such as that generated by JSONStringer. For legacy reasons this parser is lenient, so a successful parse does not indicate that the input string was valid JSON. All of the following syntax errors will be ignored: <ul> <li>End of line comments starting with // or # and ending with a newline character. <li>C-style comments starting with /* and ending with */. Such comments may not be nested. <li>Strings that are unquoted or 'single quoted'. <li>Hexadecimal integers prefixed with 0x or 0X. <li>Octal integers prefixed with 0. <li>Array elements separated by ;. <li>Unnecessary array separators. These are interpreted as if null was the omitted value. <li>Key-value pairs separated by = or =>. <li>Key-value pairs separated by ;. </ul>

Each tokener may be used to parse a single JSON string. Instances of this class are not thread safe. Although this class is nonfinal, it was not designed for inheritance and should not be subclassed. In particular, self-use by overrideable methods is not specified. See Effective Java Item 17, "Design and Document or inheritance or else prohibit it" for further information.
