+/**
+ * A JSONObject is an unordered collection of name/value pairs. Its external
+ * form is a string wrapped in curly braces with colons between the names and
+ * values, and commas between the values and names. The internal form is an
+ * object having get
and opt
methods for accessing
+ * the values by name, and put
methods for adding or replacing
+ * values by name. The values can be any of these types: Boolean
,
+ * JSONArray
, JSONObject
, Number
,
+ * String
, or the JSONObject.NULL
object. A
+ * JSONObject constructor can be used to convert an external form JSON text
+ * into an internal form whose values can be retrieved with the
+ * get
and opt
methods, or to convert values into a
+ * JSON text using the put
and toString
methods. A
+ * get
method returns a value if one can be found, and throws an
+ * exception if one cannot be found. An opt
method returns a
+ * default value instead of throwing an exception, and so is useful for
+ * obtaining optional values.
+ *
+ * The generic get()
and opt()
methods return an
+ * object, which you can cast or query for type. There are also typed
+ * get
and opt
methods that do type checking and type
+ * coercion for you. The opt methods differ from the get methods in that they
+ * do not throw. Instead, they return a specified value, such as null.
+ *
+ * The put
methods add or replace values in an object. For
+ * example,
+ *
+ *
+ * myString = new JSONObject()
+ * .put("JSON", "Hello, World!").toString();
+ *
+ *
+ * produces the string {"JSON": "Hello, World"}
.
+ *
+ * The texts produced by the toString
methods strictly conform to
+ * the JSON syntax rules. The constructors are more forgiving in the texts they
+ * will accept:
+ *
+ * An extra ,
(comma) may appear just
+ * before the closing brace.
+ * Strings may be quoted with '
(single
+ * quote) .
+ * Strings do not need to be quoted at all if they do not begin with a
+ * quote or single quote, and if they do not contain leading or trailing
+ * spaces, and if they do not contain any of these characters:
+ * { } [ ] / \ : , #
and if they do not look like numbers and
+ * if they are not the reserved words true
, false
,
+ * or null
.

+/**
+ * JSONWriter provides a quick and convenient way of producing JSON text.
+ * The texts produced strictly conform to JSON syntax rules. No whitespace is
+ * added, so the results are ready for transmission or storage. Each instance of
+ * JSONWriter can produce one JSON text.
+ *
+ * A JSONWriter instance provides a value
method for appending
+ * values to the
+ * text, and a key
+ * method for adding keys before values in objects. There are array
+ * and endArray
methods that make and bound array values, and
+ * object
and endObject
methods which make and bound
+ * object values. All of these methods return the JSONWriter instance,
+ * permitting a cascade style. For example,
+ * new JSONWriter(myWriter)
+ * .object()
+ * .key("JSON")
+ * .value("Hello, World!")
+ * .endObject(); which writes
+ * {"JSON":"Hello, World!"}
+ *
+ * The first method called must be array
or object
.
+ * There are no methods for adding commas or colons. JSONWriter adds them for
+ * you. Objects and arrays can be nested up to 200 levels deep.

+ * This can sometimes be easier than using a JSONObject to build a string.
