#5109 new enhancement

Topology documentation uses unexplained concepts

Reported by: asgerpetersen Owned by: strk
Priority: medium Milestone: PostGIS 3.5.0
Component: documentation Version: 3.2.x
Keywords: Cc:


next_left_edge is mentioned a the docs for AddFace and Polygonize in the topology documentation. For instance in it says "Note: This function does not use nor set the next_left_edge and next_right_edge fields of the edge table."

However there is no documentation of what 'next_left_edge' means and what it does. The user is left without any way of figuring out what the consequences of that note are.
