All Implemented Interfaces:

public class VOCollectionValueHolder

extends AbstractCollectionValueHolder

ValueHolder which has a Collection of ValueObjects. It provides access to a current object via an internal iterator. The next and reset methods control the position in the collection. The hasNext indicates whether there is another object in the collection (used before invoking next).

You must invoke the next() method before invoking any method which acts on the valueObject (getValueObject, getPropertyValue, setPropertyValue). The next() method will retrieve a ValueObject from the collection and hold it for access and modification.

This ValueHolder also support connection to a parentValueHolder to provide its Collection. This is used for hierarchical data representations (master/detail). To make use of this feature, set the parentValueHolder and the property name which holds the Collection in the parent via the parentPropertyName property. This object will then be notified of changes in the parent and will retrieve its new Collection.
