Hello,

 

I am in doubt whether the custom transformer I created processes just one feature at a time. It does not have any "group-by" clause active, but still seems to accumulate all the features first and then process them, instead of processing one by one.

 

Is there a way how to check this behavior?

 

Or better, is there a way how to forcingly make it feature-based instead of group-based?

 

Thank you in anticipation,

 

 

Jaroslav
Hi Jaroslav,

 

 

I think it cannot generally be said whether a custom transformer behaves like group-based transformer. A test like this could be effective to check how your custom transformer behaves:

 

  If the custom transformer behaves like group-based one, you will get {0, 1, 2, 3, 4, 0, 1, 2, 3, 4}, if not {0, 0, 1, 1, 2, 2, 3, 3, 4, 4}.   Takashi
Brilliant idea, than you.
