Thanks, rxin, this worked!
I am having a similar problem with .reduce... do I need to insert .copy()
functions in that statement as well?
This part works:
orig_graph.edges.map(_.copy()).flatMap(edge => Seq(edge) ).map(edge =>
(Edge(edge.copy().srcId, edge.copy().dstId, edge.copy().attr), 1)).collect
=Array((Edge(1,4,1),1), (Edge(1,5,1),1), (Edge(1,7,1),1), (Edge(2,5,1),1),
(Edge(2,6,1),1), (Edge(3,5,1),1), (Edge(3,6,1),1), (Edge(3,7,1),1),
(Edge(4,1,1),1), (Edge(5,1,1),1), (Edge(5,2,1),1), (Edge(5,3,1),1),
(Edge(6,2,1),1), (Edge(6,3,1),1), (Edge(7,1,1),1), (Edge(7,3,1),1))
But when I try adding on a reduce statement, I only get one element, not 16:
orig_graph.edges.map(_.copy()).flatMap(edge => Seq(edge) ).map(edge =>
(Edge(edge.copy().srcId, edge.copy().dstId, edge.copy().attr), 1)).reduce(
(A,B) => { if (A._1.dstId == B._1.srcId) (Edge(A._1.srcId, B._1.dstId, 2),
1) else if (A._1.srcId == B._1.dstId) (Edge(B._1.srcId, A._1.dstId, 2), 1)
else (Edge(0, 0, 0), 0) } )
=(Edge(0,0,0),0)
