Content link

Hi guy, 

There is no content link object exists in OOTB Windchill 11 installation.

But for content you could use:

 EPMDocument businessObject =null;
 businessObject = (EPMDocument) wt.content.ContentHelper.service.getContents(businessObject);
 Vector<?> ads = wt.content.ContentHelper.getApplicationData(businessObject);
 wt.content.ApplicationData appData;
 String desc;
 for (int i = 0; i < ads.size(); i++) {
 appData = (wt.content.ApplicationData) ads.elementAt(i);
 desc = appData.getDescription();
 if (FormatHelper.hasContent(desc) && (desc.indexOf("CONTENT") == 0 || desc.indexOf("IMAGE") == 0)) {
 wt.content.ContentServerHelper.service.deleteContent(businessObject, appData);
 }
 }

Hi @SS_14439466,

Use the following API to delete the content link.

PersistenceServerHelper.manager.remove(new WTHashSet(epmDescribeLink));

For Content CAD associations, there is no dedicated API to directly “remove the content link.” In Windchill, these associations are stored as EPMDescribeLink (passive links), not as EPMBuildRule.

The recommended approach is to retrieve and delete the link objects themselves. From the WTPart side, you can obtain the Content associations using: PersistenceHelper.manager.navigate( partWC, EPMDescribeLink.DESCRIBED_BY_ROLE, EPMDescribeLink.class, false )

(Note: the false parameter is required to return the link objects instead of only the associated CAD documents.)

You can then delete each EPMDescribeLink using: PersistenceHelper.manager.delete(link)

This is typically done on a checked-out working copy of the part, followed by a check-in, as illustrated in the Knowledge Base examples.

You can do:

QueryResult qr = PersistenceHelper.manager.navigate( partWC, EPMDescribeLink.DESCRIBED_BY_ROLE, EPMDescribeLink.class, false);

while (qr.hasMoreElements()) {
PersistenceHelper.manager.delete(qr.nextElement());
}

If you also need to remove Owner / Image / other active associations, these are stored as EPMBuildRule links and can be handled in a similar way using: EPMBuildRule.BUILD_SOURCE_ROLE

removing association will remove the link on the next iteration the link will not be deleted from existing version .

you have to use unsupported way (SQL )
