Class CmsCmisRelationHelper

java.lang.Object

org.opencms.cmis.CmsCmisRelationHelper

All Implemented Interfaces:

I_CmsCmisObjectHelper

public class CmsCmisRelationHelper
extends Object
implements I_CmsCmisObjectHelper

Helper class for CMIS CRUD operations on relation objects.

Since CMIS requires any object to have an ID by which it is accessed, but OpenCms relations are not addressable by ids, we invent an artificial relation id string of the form REL_(SOURCE_ID)_(TARGET_ID)_(TYPE).
