Constructor Detail

JSONObject

public JSONObject()

JSONObject

public JSONObject(java.util.Map<java.lang.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 java.lang.String escape(java.lang.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 java.lang.String toJSONString(java.util.Map<java.lang.String,? extends java.lang.Object> map)

toJSONString

public static java.lang.String toJSONString(java.util.Map<java.lang.String,? extends java.lang.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)

writeJSONKV

public static void writeJSONKV(java.lang.String key,
                               java.lang.Object value,
                               java.lang.Appendable out,
                               JSONStyle compression)
                        throws java.io.IOException

Write a Key : value entry to a stream

Throws:

java.io.IOException

getAsString

public java.lang.String getAsString(java.lang.String key)

A Simple Helper object to String

Returns:

a value.toString() or null

getAsNumber

public java.lang.Number getAsNumber(java.lang.String key)

A Simple Helper cast an Object to an Number

Returns:

a Number or null

                      throws java.io.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:

java.io.IOException
