No whitespace is + * added, so the results are ready for transmission or storage. Each instance of + * JSONStringer can produce one JSON text. + *

+ * A JSONStringer 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 cascade style. For example,

+ * myString = new JSONStringer()
+ *     .object()
+ *         .key("JSON")
+ *         .value("Hello, World!")
+ *     .endObject()
+ *     .toString();
which produces the string
+ * {"JSON":"Hello, World!"}
+ *

+ * The first method called must be array or object. + * There are no methods for adding commas or colons. JSONStringer adds them for + * you. Objects and arrays can be nested up to 20 levels deep. + *

+ * This can sometimes be easier than using a JSONObject to build a string. + * @author JSON.org + * @version 2008-09-18 + */ public class JSONStringer extends JSONWriter { /** * Make a fresh JSONStringer.
