- * - unsigned integer (range: 0 - Value::maxUInt)
- * - double
- * - UTF-8 string
- * - boolean
- * - 'null'
- * - an ordered list of Value
- * - collection of name/value pairs (javascript object)
- *
- * The type of the held value is represented by a #ValueType and
- * can be obtained using type().
- *
- * Values of an #objectValue or #arrayValue can be accessed using operator[]()
- * methods.
- * Non-const methods will automatically create the a #nullValue element
- * if it does not exist.
- * The sequence of an #arrayValue will be automatically resized and initialized
- * with #nullValue. resize() can be used to enlarge or truncate an #arrayValue.
- *
- * The get() methods can be used to obtain default value in the case the
- * required element does not exist.
- *
- * It is possible to iterate over the list of member keys of an object using
- * the getMemberNames() method.
- *
- * \note #Value string-length fit in size_t, but keys must be < 2^30.
- * (The reason is an implementation detail.) A #CharReader will raise an
- * exception if a bound is exceeded to avoid security holes in your app,
