And it was explicit on a previously proposed name:

Network::GetAndClearGeometries()

Yes, Pau but you should compare the size with zero in order to use the one in 
the pos file. For me is even clearer to iterate along a map and set just the 
ones that are present. At that point it is just a matter of taste.

if (posfile exist)
	load pos file
dict = network.GetAndClearGeometries()
for key, geometry in dict
	boxes[key].setGeometry(geometry)

c++ code would be not that clear but i like this procedure.
