Interface DynaBean
- All Known Implementing Classes:
- BasicDynaBean,- ConvertingWrapDynaBean,- LazyDynaBean,- LazyDynaMap,- ResultSetIterator,- WrapDynaBean
public interface DynaBean
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.
