Examples of org.springframework.beans.PropertyValue

org.springframework.beans.PropertyValue
Object to hold information and value for an individual bean property. Using an object here, rather than just storing all properties in a map keyed by property name, allows for more flexibility, and the ability to handle indexed properties etc in an optimized way.
Note that the value doesn't need to be the final required type: A {@link BeanWrapper} implementation should handle any necessary conversion,as this object doesn't know anything about the objects it will be applied to. @author Rod Johnson @author Rob Harrop @author Juergen Hoeller @since 13 May 2001 @see PropertyValues @see BeanWrapper
