Find all in and out edges from a nodes using gremlin and java

[Amrutha Valli]

Hi,

I am trying to get all the in and out nodes from the node using java and gremlin i tried bel;ow and able to get all the node ids now i want to get the properties also.

below is the  code and output

GremlinPipeline<String, List> sources =new GremlinPipeline().start((graph.getVertices("name", "HEY BO DIDDLEY"))).bothE().outV().path();

Iterator iter = sources.iterator();

   while(iter.hasNext()) {

       System.out.println("-it--"+iter.next());

   }

}

output:

-it--[v[#9:1], e[#11:0][#9:1-followed_by->#9:2], v[#9:1]] -it--[v[#9:1], e[#11:1][#9:1-followed_by->#9:3], v[#9:1]] -it--[v[#9:1], e[#11:2][#9:1-followed_by->#9:4], v[#9:1]] -it--[v[#9:1], e[#11:3][#9:1-followed_by->#9:5], v[#9:1]] -it--[v[#9:1], e[#11:4][#9:1-followed_by->#9:6], v[#9:1]] -it--[v[#9:1], e[#12:0][#9:1-written_by->#9:7], v[#9:1]] -it--[v[#9:1], e[#13:0][#9:1-sung_by->#9:8], v[#9:1]] -it--[v[#9:1], e[#11:745][#9:3-followed_by->#9:1], v[#9:3]] -it--[v[#9:1], e[#11:713][#9:5-followed_by->#9:1], v[#9:5]] -it--[v[#9:1], e[#11:2407][#9:145-followed_by->#9:1], v[#9:145]] -it--[v[#9:1], e[#11:6235][#9:124-followed_by->#9:1], v[#9:124]]

Hi,
you could try with this code

GremlinPipeline<Vertex, Vertex> sources =new GremlinPipeline().start((g.getVertices("name", "HEY BO DIDDLEY"))).bothE().outV().path();
 List<Vertex> fls3 = sources.toList();
 for(int i=0;i<fls3.size();i++){
 List<Object> l=(List<Object>) fls3.get(i);
 Vertex in=(Vertex) l.get(0);
 Vertex out=(Vertex) l.get(2);
 System.out.println(in.getProperty("yourproperty") + "  " + out.getProperty("yourproperty"));
 }

Hope it helps.

Best regards,

Alessandro

I am able to achieve this as 

GremlinPipeline<String, List> sources =new GremlinPipeline().start((graph.getVertices("name", "HEY BO DIDDLEY"))).bothE().bothV().simplePath().path();

Iterator iter = sources.iterator();

Object element =null;

while(iter.hasNext()) {

element = iter.next();

                 ArrayList<Object> newObj = (ArrayList<Object>) (element);

                 OrientVertex source = (OrientVertex) newObj.get(0);

                 OrientVertex target = (OrientVertex) newObj.get(2);

                 System.out.println("source"+source);

                 System.out.println("target"+target);

               

                 OrientEdge link = (OrientEdge) newObj.get(1);

                 System.out.println("link"+link);

}

finally if i am getting vertex id and i can get the properties from it by using graph.getVertices(rid, value).iterator().next()
