Calling Exported View Row Methods

The client program must import the package containing the Java interface for the View Row Object, the View Object row-proxy, and the generic Application Module. For example:

import package4.common.*
// includes package4.common.DeptView
// includes package4.common.DeptViewImpl

import oracle.jbo.*
// includes generic Application Module oracle.jbo.ApplicationModule

To use the exported View Row accessor methods:

1. Get an instance of the generic Application Module.

2. Get a reference to the View Row object and cast it to the View Object row-proxy containing the exported accessor method.

3. Work with the exported method.

For example:

// Call create() to get the application module instance;
// cast it to the custom application module
ApplicationModule am = session.createApplicationModule();

   // Get a reference to the View Object - Cast it to the custom  
   // view object interface containing the exported method
   ViewObject deptView = am.findViewObject("DeptView");

   // Call one of the View Object methods that return a row
   while ((row = deptView.next()) != null)

   // Cast the row to the view row interface containing the 
   // exported accessor method
   DeptViewRow deptRow = (DeptViewRow) row

   // Call the accessor method on the row
   System.out.println("DEPTNO :"+deptRow.getDeptNo());

Notice that if you are working with only the exported View Row method, you do not have to cast the Application Module to its exported interface.
