Hi,
The diagram/model xml describes the view of a diagram. A diagram can
contain edges and for those they can contain bendpoints. There is a
notation like:
<bendpoints xsi:type="notation:RelativeBendpoints"
xmi:id="_iTYCs86GEdyH2_oyoL8OSQ" points="[-20, 20, 140, -141]$[-155, 153,
5, -8]"/>
Does anybody know how this relative bendpoint notation works? Especially
the points attribute notation.
Thank You!

Hello,
You may have a look into the ConnectionViewFactory class in the
createBendpoints() method to see how these things are created.
Each point is a RelativeBendPoint (relative to the source and target
nodes position).
This notation: points="[-20, 20, 140, -141]$[-155,153, 5, -8] means that
the edge is associated with a RelativeBendpoints object which contains a
list of 2 RelativeBendpoint objects.
For the RelativeBendpoint object [-20, 20, 140, -141] you have to read
that the point is located (X=-20, Y=20) if you take the source node
location as reference point and (X=140, Y=-141) if you take the target
node location as the reference point.
Hope that will help,
Best regards,
Gilles
