How are Ports working?

[rsoika]

Hi,
can someone explain how Ports are working? I think I understand that ports are the snap points for edges of a ElementView.

How can I control the ports in my own Element View ? Can someone give a short example? The problem is that none of the GLSP source files regarding ports seems to be documented. This makes it nearly impossible to get a glue how this magic is working.

My goal is to define 4 specific ports for my visual elements to connect edges. With the default behaviour the edge can be docked at any position of a element.
Thanks for any help.

I fond a solution.

And I have also written a documentation which may be helpful: https://github.com/imixs/imixs-bpmn.glsp/blob/master/doc/PORTS.md
