public class FactoryCreateRule extends Rule
Rule implementation that uses an ObjectCreationFactory
to create
a new object which it pushes onto the object stack. When the element is
complete, the object will be popped.
This rule is intended in situations where the element's attributes are needed before the object can be created. A common scenario is for the ObjectCreationFactory implementation to use the attributes as parameters in a call to either a factory method or to a non-empty constructor.
