GetNodeEdges — Returns an ordered set of edges incident to the given node.

Sinossi

getfaceedges_returntype GetNodeEdges(varchar atopology, bigint anode);

Description

Returns an ordered set of edges incident to the given node. Each output consists of a sequence and a signed edge id. Sequence numbers start with value 1. A positive edge starts at the given node. A negative edge ends into the given node. Closed edges will appear twice (with both signs). Order is clockwise starting from northbound.

[Nota]

This function computes ordering rather than deriving from metadata and is thus usable to build edge ring linking.
