org.openlowcode.design.data.properties.basic.ConstraintOnLinkObjectSameParent<E,F>

Type Parameters:

E - left data object for the link

F - right data object for the link

All Implemented Interfaces:

NamedInterface

public class ConstraintOnLinkObjectSameParent<E extends DataObjectDefinition,F extends DataObjectDefinition>
extends PropertyBusinessRule<LinkObject<E,F>>

a constraint that will only link left and right objects if they have the same parent. This is an easy way to define working spaces in the application on objects having the same parent, the parent acting as a 'working space'
