ST_AddEdgeNewFaces — Add a new edge and, if in doing so it splits a face, delete the original face and replace it with two new faces.
integer ST_AddEdgeNewFaces(
varchar atopology, integer anode, integer anothernode, geometry acurve)
;
Add a new edge and, if in doing so it splits a face, delete the original face and replace it with two new faces. Returns the id of the newly added edge.
Updates all existing joined edges and relationships accordingly.
If any arguments are null, the given nodes are unknown (must already exist in the node
table of the topology schema) ,
the acurve
is not a LINESTRING
, the anode
and anothernode
are not the start
and endpoints of acurve
then an error is thrown.
If the spatial reference system (srid) of the acurve
geometry is not the same as the topology an exception is thrown.
