Graph.match(...) is marked @Deprecated, but the javadoc doesn't state the new preferred API usage. For instance, from Jeen in the developer discussion forum:
Graph.match() is somewhat similar to Model.filter(), though it has one important difference: filter() returns a Model again, while match() returns an Iterator. I prefer the filter() approach, I think it's far more elegant. So I would say that this is a method that should be only in Graph, and should be marked deprecated: Model.filter().iterator() is the better way to achieve the same thing.
