Network node: closed or open?

Hi everybody

I cannot find a command in manual or any similar thing that helps me to know whether certain edge of a network node is closed or not.

if that is closed then the distance between any two node which passes through that edge encompassed from the close network node must be infinity while this is not what getnetworkdistance() returns.

any comment apperciated

getedgedist(node, edgenr)

If it is a non-connect edge, it will return -1.

Do not forget reset after you change the position of network node or change property of network edge.
