How to select a particular layer in FME - Python scripting?

J

I want to convert a set of shape files to ESRI GDB format. And I need convert only the features based on the conditions in python. How to do it

Hi @jelangokvp, it's hard to provide a concrete solution since the optimal solution could be different depending on what the conditions are. And, in many cases, you can filter features easily using regular transformer(s) without Python scripting. Is there any specific reason for using Python?

No. I just want to know can it be done using Python

What are the conditions to select features?

I want select the features which overlaps with another features

It might be possible if you were an expert on computational geometry and also Python programming. It's difficult to me, so I would use a transformer to determine spatial relations between features.

Ok. Which Transformers should I use?

For example, if each feature has polygon geometry, this workflow selects every feature that overlaps, contains, is within, or is equal to other feature.
