方法详细资料

serialize

public static java.lang.String serialize(java.lang.Object object)

Serializes an object into its JSON form.

This method delegates serialization to JSONSerializers.getLegacy

参数:

object - object to serialize

返回:

String containing JSON form of the object

另请参阅:

JSONSerializers.getLegacy()

serialize

public static void serialize(java.lang.Object object,
                             java.lang.StringBuilder buf)

Serializes an object into its JSON form.

This method delegates serialization to JSONSerializers.getLegacy

参数:

object - object to serialize

buf - StringBuilder containing the JSON representation under construction

另请参阅:

JSONSerializers.getLegacy()

parse

public static java.lang.Object parse(java.lang.String jsonString)

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. Parses a JSON string representing a JSON value

参数:

jsonString - the string to parse

返回:

a Java object representing the JSON data

抛出:

JSONParseException - if jsonString is not valid JSON

parse

public static java.lang.Object parse(java.lang.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).

参数:

s - the string to parse

c - the BSONCallback to call during parsing

返回:

a Java object representing the JSON data

抛出:

JSONParseException - if s is not valid JSON
