/**
|
|
|
|
* 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.
