I am trying to return only nodes with a relationship of a given type in a
traversal using the REST API. The traversing of relationships is working
correctly, and I can successfully filter on properties, but I would like to
return only nodes with relationships of a given type, and it is not one of
the relationship types I am traversing. The problem is, every node is
showing as having no relationships in the return filter body. below is a
traverser that I have tried to use as a simplified test and got back no
results. If I add in a return true line before the current return statement,
I get back every node that has been traversed. Does getRelationships() work
in a return filter? It isn't possible that a node I have traversed to has no
relationships, so I am wondering if I am doing something wrong. the status
code is 200, the result is just an empty JSON array unless I add in code to
filter on some other criteria that returns true for some nodes.
{"order":"depth_first",
"uniqueness":"node_path",
"return filter":{
"body":"(function eval(pos) {
var node = pos.endNode();
var rels = pos.endNode().getRelationships();
var relIt = rels.iterator();
return relIt.hasNext();
})(position);",
"language":"javascript"
},
"max depth":2,
"relationships":[{"direction":"out","type":"USED"}]
}
Thanks,
Michael A
