Interface HierarchicalEntityContainer<T>

All Superinterfaces:

AdvancedFilterable, com.vaadin.data.Buffered, com.vaadin.data.Container, com.vaadin.data.Container.Filterable, com.vaadin.data.Container.Hierarchical, com.vaadin.data.Container.ItemSetChangeNotifier, com.vaadin.data.Container.Ordered, com.vaadin.data.Container.Sortable, EntityContainer<T>, Serializable

All Known Implementing Classes:

JPAContainer

public interface HierarchicalEntityContainer<T>
extends EntityContainer<T>, com.vaadin.data.Container.Hierarchical

This is a preliminary interface for adding hierarchical support to JPAContainer. It works if the entities can be nested by means of a parent property, e.g. like this:

 class MyNodeEntity {
   MyNodeEntity parent;
   ...
 }
 

Since:

1.0
