How do I get the BOTH ends of a user-created sketch line segment?

Suppose the user has created a sketch, and on that sketch has created a line segment. Further, assume I have this as an input to my feature :
Now, i'd like to access that linesegment from within featureScript. I can't figure out how to do it.
I can get the sketch Plane on which the line resides:
annotation { "Name" : "UserLine","Filter" : GeometryType.LINE,"MaxNumberOfPicks" : 1 }
definition.userLine is Query;I can get the sketch Plane on which the line resides:
var sketchPlane = evOwnerSketchPlane ( context, { entity: definition.userLine } ); ..And I can get the line definition using evLine:
var line = evLine(context, {
"edge" : definition.userLine
});But this line definition only gives me the starting point of the line segment the user created, not the ending. But i need to get the beginning and ending of the user's line segment. How can I do that?
I have tried toString() to see if I can access properties of the object I get as a result of evaluateQuery, but that doesn't help me.
There do not appear to be any examples in std of getting a sketch entity this way.

Two ways to do this:
You can use evEdgeTangentLines and pass [0,1] as the parameters argument (0 means start, 1 means end)
or:
you can use qVertexAdjacent(definition.userLine, EntityType.VERTEX) to query for the two endpoint vertices and then call evVertexPoint on each of them.Ilya Baran \ VP, Architecture and FeatureScript \ Onshape Inc5

Thanks for the fast answer!
