Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args) ⇒ Object

This method is invoked by Ruby when a method that is not defined in this instance is called.

In our case we inspect the @method@ parameter and try to find the attribute, simple descendent or collection that it maps to in the XML tree.
