Hi Andrey,
On a related issue, I am not able to create edges by RID retrieved from
indexes. Please help
----------------_Error-------------------------------
error: method addEdge in class OrientBaseGraph cannot be applied to given
types;
graph.addEdge("class:e1", v1,clsVertex,"e1");
^
required: Object,Vertex,Vertex,String
found: String,ORID,OrientVertex,String
-------------------------------------------------------
Code is Like:
-----------------------------------
OrientVertex clsVertex = graph.addVertex("class:mc1", "ID","data1f");
clsVertex.save();
graph.addEdge("class:e1", (ORID)luke.get(0),clsVertex,"e1");
--------------------------------------------
