How to check if downstream view of the WT part exists?

How to check if downstream view of the WT part exists?

Hi All,

I want to create a "Manufacturing" view for the part included in the Change task, but I want to do it only if it doesn't exist.

Now I use this code without checking. And I want to add something like " if Manufacturing view for obj ==null then" 

 

wt.fc.QueryResult qr = wt.change2.ChangeHelper2.service.getChangeablesBefore((wt.change2.ChangeOrderIfc) primaryBusinessObject);

while(qr.hasMoreElements())

{

  wt.fc.WTObject  obj =(wt.fc.WTObject) qr.nextElement();

   if(obj instanceof wt.part.WTPart)

      {

       wt.part.WTPart prt = (wt.part.WTPart) obj;

       wt.part.WTPart ManufPart = (wt.part.WTPart)

       ManufPart = (wt.vc.views.ViewManageable)obj, "Manufacturing")

       wt.vc.views.ViewHelper.service.newBranchForView((wt.vc.views.ViewManageable)obj, "Manufacturing");

 

      ManufPart = (wt.part.WTPart)wt.fc.PersistenceHelper.manager.store(ManufPart);

       }

  }

Hi @Dina_S 

It is easy.

Filter the results based on your view

 

QueryResult qrUstr = PersistenceHelper.manager.navigate(part,EquivalenceLink.DOWNSTREAM_ROLE,wt.associativity.EquivalenceLink.class, true);

		WTPart dwWTP = null;
		while (qrUstr.hasMoreElements())
		{
			dwWTP = (WTPart) qrUstr.nextElement();
			if (dwWTP.getViewName().equalsIgnoreCase("manufacturing"))
			{
				System.out.print(dwWTP.getNumber()); // use it as you need. 
			}
		}

I have found this

https://www.ptc.com/en/support/article/cs47538?language=en&posno=4&q=ViewHelper.service.newBranchForView&source=search

 

wt.fc.PersistenceHelper.manager.navigate(reference.getObject(),wt.associativity.EquivalenceLink.DOWNSTREAM_ROLE, wt.associativity.EquivalenceLink.class);

 

I need help finding out how to use this. I need only the "Manufacturing view" part, not the "Service view" one. And I don't know how to check the assigned view for the object. I would really appreciate it if someone could help me.

 

So I tried this and it doesn't work like I want:

 

wt.fc.QueryResult AllDownPart = wt.fc.PersistenceHelper.manager.navigate(obj,

wt.associativity.EquivalenceLink.DOWNSTREAM_ROLE, wt.associativity.EquivalenceLink.class,true);

 

if(AllDownPart != null){

Thank you for the clue.

It is also important not to forget to create an Equivalence link.
The object is taken from Change Notice.
Below full working code without checking procedures:

 

wt.fc.QueryResult qr = wt.change2.ChangeHelper2.service.getChangeablesBefore((wt.change2.ChangeOrderIfc) primaryBusinessObject);
	//qr changeable before= vector all Deign part for Manufacturing
while(qr.hasMoreElements())
{
   wt.fc.WTObject  obj =(wt.fc.WTObject) qr.nextElement();
   //obj =one design part from implementation tasks
   if(obj instanceof wt.part.WTPart)
	{
	   wt.part.WTPart prt = (wt.part.WTPart) obj;
	   wt.fc.QueryResult AllDown = wt.fc.PersistenceHelper.manager.navigate(prt, wt.associativity.EquivalenceLink.DOWNSTREAM_ROLE, wt.associativity.EquivalenceLink.class,true);
	//all downstream parts

	   wt.part.WTPart ManuPart= null;
	// empty part for Manufacturing

	  wt.part.WTPart dwWTP = null;
   // empty part for checking if Manufacturing

	 while (AllDown.hasMoreElements())
		{
			dwWTP = (wt.part.WTPart) AllDown.nextElement();
			if (dwWTP.getViewName().equalsIgnoreCase("Manufacturing"))
			{
				System.out.print(dwWTP.getNumber()); 
				ManuPart = dwWTP;
			}
	    }
	if(ManuPart==null)
	   {
	  ManuPart = (wt.part.WTPart)wt.vc.views.ViewHelper.service.newBranchForView((wt.vc.views.ViewManageable)prt, "Manufacturing");
	  ManuPart = (wt.part.WTPart)wt.fc.PersistenceHelper.manager.store(ManuPart);
	  //create equivelencelink between these 2 parts
		wt.associativity.EquivalenceLink link1 = wt.associativity.EquivalenceLink.newEquivalenceLink(prt,ManuPart);
		link1.setIsConsumable(true);
		link1.setUpstreamContextRef(prt.getView());
		link1.setDownstreamContextRef(ManuPart.getView());
		link1 = (wt.associativity.EquivalenceLink) wt.fc.PersistenceHelper.manager.save(link1);
		}
 
	}
}

 I also found that it is important not to forget to create EquivalenceLink :).
