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

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,? extends Object> map)

toJSONString

public static String toJSONString(Map<String,? extends Object> map,
                                  JSONStyle compression)

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.

Parameters:

map -

Returns:

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

See Also:

JSONValue.toJSONString(Object)

writeJSON

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

Throws:

IOException

writeJSON

public static void writeJSON(Map<String,? extends Object> map,
                             Appendable out,
                             JSONStyle compression)
                      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)

public void writeJSONString(Appendable out)
                     throws IOException
