RE: [mylar-dev] example implementation ofIGraphContentProviderinterface/ what are relationships
|
Ian: could you answer Raphael's question?
Raphael: sorry that you still haven't seen an answer to this--I pinged Ian a
while back but he may be on vacation. Fyi, the Mylar visualization
prototype was using the relationship objects to encapsulate the kind of edge
between two nodes (e.g. Java call, inheritance).
