TinkerPop 3 Gremlin在遍历期间收集边缘属性

使用TinkerPop 3 Java API:

我的图表如下:

james {risk: 'n'} --> chris {risk: 'n'} --> raj {risk: 'n'} --> joanne {risk: 'y'}

The edge label is 'travelledWith' and a property called 'pnrLocator'

这就是我所拥有的,它只适用于顶点属性。如何添加“by”并收集“pnrLocator”?

GraphTraversal<Vertex, ?> values =
                g.traversal()
                        .V()
                        .has("personId", "james")
                        .repeat(out("travelledWith"))
                        .until(has("risk", "y"))
                        .limit(100)
                        .path()
                        .by("personId");


        values.forEachRemaining(v -> System.out.println(v));
