Jake Mannix commented on GIRAPH-31:
-----------------------------------

Avery, Dmitriy - after thinking about it, I think both true and false are 
wrong!  BasicVertex shouldn't implement this method at all, leave it abstract, 
and sublcasses which implement iterator() are forced to also tell users whether 
it chose to implement it sorted or not.  

> Hide the SortedMap<I, Edge<I,E>> in Vertex from client visibility (impl. 
> detail), replace with appropriate accessor methods

> As discussed on the list, and on GIRAPH-28, the SortedMap<I, Edge<I,E>> is an 
> implementation detail which needs not be exposed to application developers - 
> they need to iterate over the edges, and possibly access them one-by-one, and 
> remove them (in the Mutable case), but they don't need the SortedMap, and 
> creating primitive-optimized BasicVertex implementations is hampered by the 
> fact that clients expect this Map to exist.
