Package com.jcorporate.expresso.core.controller Description

This package contains the object defining the "Controller" object, an important component of Expresso that should be used to encapsulate all user interaction sequences.

Controllers are the guts Expresso's logic system. You derive your own controller class from DBController to automatically get features such as built in per-state security.
