public class ReferentialIntegrityException
extends DataIntegrityException

A data integrity exception that indicates an attempt to create stale references. A stale reference is a refenrence that points to a target object that does not (or no longer) exist.

Detection of referential integrity violations must be explicitely enabled on the server side because it can be expensive:

    <property name="ensureReferentialIntegrity" value="true"/>
 

The risk of referential integrity violations can be reduced (but not eliminated) by using local cross reference queries before committing:

• CDOView#queryXRefs()
• CDOView#queryXRefsAsync()
