Q:

How to loop over verticies in Gremlin and adding edge

I'm trying to figure out how to loop over verticies within a container and adding edges between the current vertice in the loop and a given vertice.
This is what I have so far:
This gives me an array of all vertice id's within the given container:
v=g.V('containerName','MyContainer').outE.inV.id

result:
{"results":[12,320004,280004,240004,200004,160004,120004,80004,40004],"success":true,"version":"2.4.0","queryTime":35.089565} 

Now I want to loop/iterate over all the id's in this array, get the vertice of the id and add an edge between a given vertice and the current vertice in the loop.
Anyone that knows how this can be done?

A:

You can make a sideEffect that adds the new edges.
With the toy tinker graph:
g = TinkerGraphFactory.createTinkerGraph()

let's assume you want to link peter to all neighbors of marko (out only)
givenVertex = g.V('name','peter').next()
g.V('name','marko').out.sideEffect{g.addEdge(givenVertex,it, 'yourLabel')}

verify result:
g.V('name','peter').out.name
==>lop // lop appears twice because edge peter -> lop was present previous to operation
==>lop
