All Implemented Interfaces:

DataModel

public class JavaBeanDataModel

extends DefaultDataModel

A class that creates a collection of MetaData based BeanInfo PropertyDescriptors. To use this class:

1. Construct the model using the Bean class you wish to model
2. use setJavaBean to set the current object of this class.
3. Updates made to the form will update the property values of the bean.

TODO: Using JavaBeans as a data source should be generalized and not constrained to FormModels.
