(Please mail to the list so that others will be able to find answers to 
similar questions later.)

The only thing special that DirectedMultigraph does is super(ef, true, 
true).  The extra parameters set allowMultipleEdges=true and 
allowLoops=true.  So you just need to do the same in your 
ListenableDirectedMultigraph constructor, which should extend 
DefaultListenableGraph and implement DirectedGraph (just copy 
ListenableDirectedGraph).
