  • Ticket #4934 – Description

    initial v1  
    55Such functions are (list to be grown I guess):
    66
    7  - topology.AddEdge (does not do edge linking nor face labeling)
     7 - AddEdge (does not do edge linking nor face labeling)
     8 - AddNode (allows inserting isolated nodes with wrong containing_face)
     9
     10
     11Another idea would be to *allow* creating invalid topology but somehow encode the kind of invalidity when doing so. For example in the AddLineStringNoFace function used as part of the proposed https://git.osgeo.org/gitea/postgis/postgis/pulls/28 change we encode the concept of "unknown side faces" by using the -1 pivot value in the left_face and right_face of edges with such unknown faces.
