Class DBMaint

java.lang.Object
  org.apache.struts.action.Action
      com.jcorporate.expresso.core.controller.Controller
          com.jcorporate.expresso.core.controller.DBController
              com.jcorporate.expresso.services.controller.DBMaint

All Implemented Interfaces:

Serializable

public class DBMaint

extends DBController

Controller that enables basic maintenance (add/update/delete) of any DBObject DBMaint acts more as a controller for allowing operations on DBObjects. The real work for adding, deleting, searching and updating is carried out by a series of classes that are dynamically instantiated and live in the com.jcorporate.expresso.core.servlet.commands package. These classes can be extended to add additional functionality.

When tracking down code functionality, the core states are in package:
com.jcorporate.expresso.services.dbmaint

The only state handlers embedded in the class are minimalistic classes for allowing admins to select the DBObjects to administer from dropdown lists.
