| DynaBean | | public interface DynaBean (Code) | | A DynaBean is a Java object that supports properties
whose names and data types, as well as values, may be dynamically modified.
To the maximum degree feasible, other components of the BeanUtils package
will recognize such beans and treat them as standard JavaBeans for the
purpose of retrieving and setting property values.
