public class NamedConstructorArgs
extends Object

NamedConstructorArgs is a BeanFactoryPostProcessor that converts property declarations into indexed constructor args based on the the constructor parameter names annotation. This process first selects a constructor and then fills in the constructor arguments from the properties defined in the bean definition. If a property is not defined in the bean definition, first the defaultValues map is checked for a value and if a value is not present a Java default value is provided for the constructor argument (e.g. numbers are assigned 0 and objects are assigned null).
