- * 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
- * property with the corresponding name exists. If found, the property gets the value.
