The default implementation of the IlpDataSource interface provides an API that
directly supports JavaBeans™ objects. This API transforms JavaBeans
objects into IlpObject instances of type IlpBeansObject.
If necessary, see Reminder about JavaBeans design patterns.
The example below shows how to add JavaBeans objects to a data
source. It reuses the
MO
class defined in Defining the business model from JavaBeans
classes. Objects are created as regular Java™ objects, inserted in
a data source, and modified by means of their set methods.
How to add JavaBeans objects to a data source
MO mo1 = new MO("mo1");
dataSource.addBean(mo1,"mo1");
mo1.setState(2);
Once in the data source, these objects can be displayed in the
various JViews TGO
graphic components. Bound property updates are dynamically
reflected in these components.
The figure below shows an
MO
object displayed in a tree component.

component
Note
The graphical result depends also on the style information
associated with the object. Here, the state attribute is mapped
to a color. For details, see Introducing cascading style sheets.
