Method Detail

serialize

public static String serialize(Object o)

Serializes an object into its JSON form.

This method delegates serialization to JSONSerializers.getLegacy

Parameters:

o - object to serialize

Returns:

a String containing the JSON form of the object

See Also:

JSONSerializers.getLegacy()

serialize

public static void serialize(Object o,
             StringBuilder buf)

Serializes an object into its JSON form.

This method delegates serialization to JSONSerializers.getLegacy

Parameters:

o - object to serialize

buf - StringBuilder containing the JSON representation under construction

See Also:

JSONSerializers.getLegacy()

parse

public static Object parse(String s)

Parses a JSON string and returns a corresponding Java object. The returned value is either a DBObject (if the string is a JSON object or array), or a boxed primitive value according to the following mapping:

java.lang.Boolean for true or false
java.lang.Integer for integers between Integer.MIN_VALUE and Integer.MAX_VALUE
java.lang.Long for integers outside of this range
java.lang.Double for floating point numbers

If the parameter is a string that contains a single-quoted or double-quoted string, it is returned as an unquoted java.lang.String.

Parameters:

s - the string to parse

Returns:

a Java object representing the JSON data

Throws:

JSONParseException - if s is not valid JSON

parse

public static Object parse(String s,
           BSONCallback c)

Parses a JSON string and constructs a corresponding Java object by calling the methods of a BSONCallback during parsing. If the callback c is null, this method is equivalent to parse(String).

Parameters:

s - the string to parse

c - the BSONCallback to call during parsing

Returns:

a Java object representing the JSON data

Throws:

JSONParseException - if s is not valid JSON
