Fetching all trees

[Ankur Goel]

Hi,

i have a graph with following connection ex:

1. n1--> n2--->n3
   
2. n4-->n5
   
3. n5
   

Where n represent node and line between them is edge.

What i am looking janus query should return all connected tree. Does Janus support this?

In above graph it should return 3 trees.

Hi Ankur,

You can experiment witth the repeat step:

gremlin>  g=TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V().emit().repeat(out()).times(2).path().by('name')

Thnx Marc,

I am also using this, but with this, mentioned query should be aware about all possible connections between vertices in a connected graph. 

Pros: with this approach if any new edge connection happen than for each we have to alter query, time is another dimension also.

I am looking a method that give me all different connected graph by  any vertices without knowing intricacy of the graph: just all connected vertex.

Check out the connected components recipe.
