Hello dear paraview developers!
I have a tremendously imporant question.
How can one receive from the given pipeline element, the list of fields, and the data, corresponding to that field?
My best regards

You dont really want that, that means transporting the data from the server to the client.

Are Source Proxies applicable to filters?

What should I do if I want to pass for example, 100 values from the server to the client?
How could I achieve that?

You do not want to do that in general, if needed, you can use an information property.

Could you please advise me where to search for an example?

It works well, when I insert a specific function in my own filter
Is there a way to do the same with any given source/filter without modifying it?

Not the same. However you can fetch the data with the `ClientServerMoveData` filter and use `GetClientSideObject`, keep in mind it can be very costly.
Look for example implementation in `vtkSpreadSheetView::StreamToClient()`

Dear Mathieu, could you please explain, could GetClientSideObject be used without ClientServerMoveData?

Yes, when you are in “builtin” mode, GetClientSideObject always provide the server side object as the server and the client are actually a single executable and share a the same memory space.
