changing direction of edges

[iliana avila]

What is the easiest way of flipping the direction of an edge programatically?

If my graph looks like this (there is an actual arrow defined by a
visual style):

a ----> b

I want to make it look like this:

a <---- b

Is the easiest way removing the edge and creating a new one with
switched node order and then copying all the edge attributes from the
old one to the new one?

Thanks.

yes that is the best way,

if we allow for edge direction to change, then it potentailly messes
up algorithms that expect an edge to be a certain direction.
