java.lang.Objectjava.util.AbstractMap
java.util.HashMap
com.ibm.json.java.JSONObject
com.ibm.json.java.OrderedJSONObject
Extension of the basic JSONObject. This class allows control of the serialization order of attributes.
The order in which items are put into the instance controls the order in which they are serialized out. For example, the
last item put is the last item serialized.
JSON-able values are: null, and instances of String, Boolean, Number, JSONObject and JSONArray.
Instances of this class are not thread-safe.

public static JSONObject parse(java.io.Reader reader) throws java.io.IOException
reader
- The reader from which the JSON data is read.
IOEXception
- Thrown if an underlying IO error from the reader occurs, or if malformed JSON is read,
java.io.IOException
public static JSONObject parse(java.lang.String str) throws java.io.IOException
str
- The JSON string to parse into a Java Object.
IOEXception
- Thrown if malformed JSON is read,
java.io.IOException
public static JSONObject parse(java.io.InputStream is) throws java.io.IOException
is
