Deleting an Edge

You can use a specific API provided by GES to delete an edge. The sample code is as follows:

public static void deleteEdge(GraphClient graphClient) throws ApiException
{
  DeleteEdgeReq deleteEdgeReq = new DeleteEdgeReq();
  deleteEdgeReq.setSource("Lily");
  deleteEdgeReq.setTarget("Rocky");
  deleteEdgeReq.setIndex(0);
  graphClient.deleteEdge(deleteEdgeReq);
}
