How to access the contents of an Edge object

With a Vertexes object I see its contents if I type
for instance.
What is a similar method for access the information stored in the Edge object?
I've searched though the TopoShape API but with no success.

for instance, in FreeCAD 0.17 (daily)
Code: Select all
>>> lineSegment = Part.LineSegment()
>>> edge = lineSegment.toShape()
>>> edge.Curve
<Line object>
>>> edge.FirstParameter
0.0
>>> edge.LastParameter
1.0
>>> edge.Length
1.0
>>> edge.Orientation
'Forward'
>>> edge.ParameterRange
(0.0, 1.0)
>>> edge.firstVertex().Point
Vector (0.0, 0.0, 0.0)
>>> edge.lastVertex().Point
Vector (0.0, 0.0, 1.0)
I think to remember that this query was a little bit more difficult with FreeCAD 0.16

I'm using 0.16 and there is no firstVertex().Point attribute. Is there another way collecting the start end data of an Edge in a Part?
Also is there a full list of attributes & methods somewhere or this still an on going documentation thing?

Thanks that's exactly what I was after.
