Hello Matteo,
As far as I know, if your algorithm :
does not change the table structure (geometry type, fields list and
their types)
is an instance of QgsProcessingFeatureBasedAlgorithm (output one
feature for each input feature)
In brief:
- If your algorithm output one feature for each input feature:
=> your should inherit from QgsProcessingFeatureBasedAlgorithm.
- If your outputs features have same geometry type and same fields
with same types:
=> you can put the flag on your algorithm as it can be used for
in place editing.
When in place editing is checked in dialog, output features replace
input features in source instead of being appended to an output.

Hi all,
is it possible to write a custom Processing script that can edit the
input layer in place (with the core functionality of course)?
In the documentation I found the method to check if the algorithm
supports the in place editing [0] but not the method to set the script
to support the functionality.
There are a few python core algorithms with
Thanks for any hint!
Cheers
Matteo
