public interface IDataBean
extends IDataObject

A data bean is an extension of the IDataObject interface to provide a dynamic JavaBean-type object. Like a JavaBean, a data bean has only string property names. Unlike a JavaBean, a data bean's properties are not fixed: properties can be created and deleted on the fly. Property values can also be dynamically set to be transient/non-transient.

Data beans also add the guarantee of being able to conveniently set/get primitive values via specialised methods (this is also provided by AbstractDataObject but is not part of the IDataObject interface to simplify implementations that aren't based on this class).

Standard JavaBeans can be adapted as data beans using either JavaDataBean or SimpleJavaDataBean.

Method Detail

getPropertyNames

String[] getPropertyNames()

Databean's only have strings as their property names. This is a shortcut to get the property names for which getValue () would return a non-null value.
