This is the world of split and merge. The syntax for this is not the sexiest,
but as it stands:
g.v(0)._.copySplit(_().out('Friends'), _().in('Likes')).fairMerge
copySplit will take what comes into it and copy it to its internal pipes (in
this case, 2 internal pipes). Then fairMerge will, in a round robin fashion,
merge the output of the two internal pipes into a single pipe. Thus, split the
pipeline, then merge it back into a single pipeline.
For example, over the play TinkerPop graph:
gremlin> g = TinkerGraphFactory.createTinkerGraph()
==>tinkergraph[vertices:6 edges:6]
gremlin> g.v(1)._.copySplit(_().out('created'),_().out('knows')).fairMerge
==>v[3]
==>v[2]
==>v[4]
We haven't developed split/merge much. If you have any ideas for syntax, that'd
be great.
NOTE: If they were both out, then you can simply do:
g.v(0).out('friends','likes')
Good luck,
Marko.
