Hi, I have a question regarding InterfaceLinkFilter. That class is
intended to prevent the visualization of litter required interface links.


First of all, I'am a bit puzzled about the meaning of derived and genuine
links.
Well, in uml2 metamodel the property requireds is derived both for the
port and for the component since the required interfaces for a component
may be the interfaces that are required by its public ports and the port
take his interfaces from his type (a classifier). However, as I understand
in InterfaceLinkManager a derived link is merely a link from a port and a
genuine link is a link from a component.

I am supposing I'm true about what derived or genuine means for
InterfaceLinkFilter.

I have tested the funcionality both in 0.8 and 0.9M5 and it only manages
to hide the so called derived links. Moreover, in 0.9M5 if a port exist
the genuine link are never shown because it is managed with custom code in
diagramUpdater. ┬┐Why don't use InterfaceLinkFilter (And properties page)
to manage that links instead of modifying diagramUpdater? We can achieve
the same goal modifying subclases of InterfaceLinkFilter.
