ST_AddIsoEdge — Adds an isolated edge defined by geometry alinestring
to a topology connecting two existing isolated nodes anode
and anothernode
and returns the edge id of the new edge.
integer ST_AddIsoEdge(
varchar atopology, integer anode, integer anothernode, geometry alinestring)
;
Adds an isolated edge defined by geometry alinestring
to a topology connecting two existing isolated nodes anode
and anothernode
and returns the edge id of the new edge.
If the spatial reference system (srid) of the alinestring
geometry is not the same as the topology, any of the input arguments are null, or the nodes are contained in more than one face, or the nodes are start or end nodes of an existing edge,
then an exception is thrown.
If the alinestring
is not within the face of the face the anode
and anothernode
belong to, then an exception is thrown.
If the anode
and anothernode
are not the start and end points of the alinestring
then an exception is thrown.
