Overview

A Controller class or a duck-typed alternative should be created and registered with a Shell for any type that implements behavior other than the default REST API processing.

When a request arrives at the Shell, the expected Controller method is identifed and a check is made to verify if the Controller responds to the method. If it does not, then the handle method is called. Since respond_to includes only public methods, only those methods made public in a Controller subclass are considered. The candidates for making public are create, read, update, and delete.

A description of the available methods is included as private methods.
