- * Converts between objects with getter and setter methods and arrays.

- * The normalization process looks at all public methods and calls the ones
- * which have a name starting with get and take no parameters. The result is a
- * map from property names (method name stripped of the get prefix and converted
- * to lower case) to property values. Property values are normalized through the
- * serializer.
- *
- * The denormalization first looks at the constructor of the given class to see
- * if any of the parameters have the same name as one of the properties. The
- * constructor is then called with all parameters or an exception is thrown if
- * any required parameters were not present as properties. Then the denormalizer
- * walks through the given map of property names to property values to see if a
- * setter method exists for any of the properties. If a setter exists it is
- * called with the property value. No automatic denormalization of the value
- * takes place.
