Constructor Detail

JSONObject

public JSONObject()

JSONObject

public JSONObject(Map<String,?> map)

Allows creation of a JSONObject from a Map. After that, both the generated JSONObject and the Map can be modified independently.

Method Detail

cast

public <T> T cast()

Allow simply casting to Map

escape

public static String escape(String s)

Escape quotes, \, /, \r, \n, \b, \f, \t and other control characters (U+0000 through U+001F). It's the same as JSONValue.escape() only for compatibility here.

See Also:

JSONValue.escape(String)

toJSONString

public static String toJSONString(Map<String,Object> map)

Convert a map to JSON text. The result is a JSON object. If this map is also a JSONAware, JSONAware specific behaviours will be omitted at this top level.

Returns:

JSON text, or "null" if map is null.

See Also:

JSONValue.toJSONString(Object)

toString

public static String toString(String key,
                              Object value)

writeJSONString

public static void writeJSONString(Map<String,Object> map,
                                   Appendable out)
                            throws IOException

Encode a map into JSON text and write it to out. If this map is also a JSONAware or JSONStreamAware, JSONAware or JSONStreamAware specific behaviours will be ignored at this top level.

Throws:

IOException

See Also:

JSONValue.writeJSONString(Object, Appendable)

writeJSONString

public void writeJSONString(Appendable out)
                     throws IOException

serialize Object as json to an stream

Throws:

IOException

merge

public void merge(Object o2)

merge

protected static JSONObject merge(JSONObject o1,
                                  Object o2)

merge

protected static JSONArray merge(JSONArray o1,
                                 Object o2)

toJSONString

public String toJSONString()

Specified by:

toJSONString in interface JSONAware

Returns:

JSON text

toString

public String toString()

Overrides:

toString in class AbstractMap<String,Object>
