How do I create a repetitive workflow?

The super quick answer would be to use a custom transformer with a Transformer Loop inside it. Then if you create a work flow that does its business inside the CT you can just repeat with the loop until you are out of points.

I'm wondering if doing this recursively is the best way to go in in FME (it would be in a standard programming language).

What about determining the largest circle size in the dataset. Use a NeighborFinder (candidates only, with the Maximum Distance set to the largest circle size and generating a list containing the rank number and circle size.

If any of the elements match those two criteria, discard the feature.

I would not try to do this in a loop.

I would create circles for all points.

Then use a PointonAreaOverlayer to find all points within the circles (generate a list).

If Circles contain no points with lower rank, add the circle to the list.

Hope this helps.

Hi Erik,

I have tried this before but unfortunately it doesn't work because of the following case:

Using PointOnAreaOverlayer will drop the point with rank = 8 because of rank = 9. That's why it's very important to do it in order

No, in the above example with an PointOnAreaOverlayer, the ranks lists should be as follows:

why 8: 8? Doesnt it also contain rank 9?

No, you are comparing the point to the circles it falls in.

Actually, if you replace rank = 9 with 12 then this method doesn't work right? it's because 8 & 9 will be selected

If you replace 9 with 12 then you would have

That's not correct though because I want to select the highest rank first (12) go to the second highest (11) and see if its circle contains 12, if so it shouldn't be selected.

Oh, I assumed that the highest rank was the lowest number.
