Each instance of - * JSONWriter can produce one JSON text. - * <p> - * A JSONWriter 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 a cascade style. For example, <pre> - * new JSONWriter(myWriter) - * .object() - * .key("JSON") - * .value("Hello, World!") - * .endObject();</pre> which writes <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. JSONWriter adds them for - * you.
