[vtkusers] VTK 6 Migration - GetProducerPort in SetNthInputConnection replacement

[Nicole Kovacs]

It is actually supposed to make a pipeline connection. You're right, my mistake to think SetInputData() would work.


What do you mean by "you can simply pass data objects if you want to connect pipelines anymore"? I tried doing:

someAlgorithm->SetNthInputConnection(port, index, *someDataObject);

but it didn't work.


Also, by "refactored" do you mean using just SetInputConnection?

Is this call supposed make a pipeline connection? Note that SetNthInputConnection() makes a pipeline connection whereas SetInputData() and variants do not. Once you figure it out, if SetInputData() is still good, I can share a way of doing what you want. If not, this code will have to be refactored. You can simply pass data objects if you want to connect pipelines anymore.

Hi guys,


I apologize if this is a basic question, I'm new to VTK and I'm trying to port some VTK code from version 5.x to version 6.x


I'm facing various errors regarding GetProducerPort's removal from vtkDataObject. I know that I should be replacing someAlgorithm->SetInputConnection(someDataObject->GetProducerPort());
by someAlgorithm->SetInputData(someDataObject);


but the code I have is a bit different, such as:
someAlgorithm->SetNthInputConnection(port, index, someDataObject->GetProducerPort());


I thought about looking for some SetNthInputData method that takes as arguments a port and an index and could solve my problem, but haven't found anything that useful. I did find a method called SetInputDataObject(int port, vtkDataObject *data) that has the port, but not the index.


Is there a way that I can port this part of my code? Is there a reason that SetInputData methods don't have indices as arguments?


I have talked to the author of the code I'm porting and I know that in some cases I don't need to specify the port, only the input index. Is there a method that does that?


Thank you for your attention!
