Gelly contains a set of MapFunction between Vertex and Tuple2 and between Edge and Tuple3. A Vertex is a Tuple2 and an Edge is a Tuple3, and conversion in the opposite direction can be performed with a single object per MapFunction. This only applies to the Gelly Java API. Scala tuples are not related to Vertex or Edge.
