重新运行Tinkerpop图中的现有路线 [英] Re-running an existing route in a Tinkerpop Graph

问题描述

如果我有一条从shortestPath出发的预先运行路线，该路线作为顶点列表返回，那么我该如何在具有相同顶点集的图形上重新运行该路线，以返回其已使用的边.

If i have a pre-run route from the shortestPath which is returned as a list of vertex, how can i then re-run that on a graph with the same set of vertices, to return the edges which it has used.

即PATH =(V(1)，V(2)，V(3)，V(4)，V(5)，V(6))，该命令将如何在相同的新图上重播该路径顶点，返回包含不同属性的边.

i.e. PATH = (V(1), V(2), V(3), V(4), V(5), V(6)), how would the command look to replay that path on a new graph with the same vertices, returning the edges, which contain different properties.

所以要确认我需要输入此显式路径以返回边?

So to confirm i need to input this explicit Path to return the edges?

推荐答案

如果我知道我的路径是[v[1],v[4],v[3]，我想我会建立这样的东西:

If I knew my path was [v[1],v[4],v[3] I suppose I would just build something like this:

gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V(1).out().hasId(4).out().hasId(3).path()
==>[v[1],v[4],v[3]]

由于您的路径可能具有可变长度，所以我想我会循环遍历并动态构造遍历，为路径中的每个顶点添加一个out().hasId().

Since your path may be of variable length I suppose I would just cycle through it and dynamically construct the traversal adding a out().hasId() for each vertex in the path.
