Each instance of + * JSONStringer can produce one JSON text. + * <p> + * A JSONStringer instance provides a <code>value</code> method for appending + * values to the + * text, and a <code>key</code> + * method for adding keys before values in objects. There are <code>array</code> + * and <code>endArray</code> methods that make and bound array values, and + * <code>object</code> and <code>endObject</code> methods which make and bound + * object values. All of these methods return the JSONWriter instance, + * permitting cascade style. For example, <pre> + * myString = new JSONStringer() + * .object() + * .key("JSON") + * .value("Hello, World!") + * .endObject() + * .toString();</pre> which produces the string <pre> + * {"JSON":"Hello, World!"}</pre> + * <p> + * The first method called must be <code>array</code> or <code>object</code>. + * 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. + * <p> + * 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.
