-/**
- * 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.
- * <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. 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.
