Peter,
there is no concept of END_OF_GRAPH in Neo4j or Gremlin. It is merely
the concept of not including a depth-related component into the stop
condition of a traversal. So, your query could maybe be something like
g.v(%d).out('JOURNEY').loop(1){it.object.getProperty('stop_id') !=
'%d'}.out('HOP').paths
Note the shorter notation of steps that simply filter by direction and
label of the edges. Does this work? Also, you might need to take into
account that the stop_id might not be present on some nodes in your
closure?
Cheers,
