Triggered by out of memory errors when working with a lot of GeoDataFrames.
It seems that
iterate
just allocatesFeature
s without anyone ever cleaning them. This PR introduces anIFeature
(and its parentAbstractFeature
), which should align nicely with the other types.Since GeoDataFrames goes through quite some calls, it is a bit hard to find these things, but I expect this is not the only memory leak remaining.
