Hi,
I am trying to create a traverser and I am stuck.
So my code takes in a startNode, 2 relationshiptypes and 2 directions.
It will starting from startNode go to nodes with rel1 in dir1 and from all
those nodes to rel2,dir2.
The code below (in SCALA) works fine and I get the expected nodes.
The issue is, along with the nodes I also need to get properties from the
relationships. So all my relationshiptypes have certain properties (key,
value), what I want is to get a particular property from rel1 and rel2. How
do I do that?
def traverser(node: Node, rel1: RelationshipType, rel2: RelationshipType,
dir1: Direction, dir2: Direction) = {
val q1 = node.traverse(Order.BREADTH_FIRST, StopEvaluator.DEPTH_ONE,
ReturnableEvaluator.ALL_BUT_START_NODE, rel1, dir1).iterator()
while(q1.hasNext){
val n = q1.next()
val q2 =
n.traverse(Order.BREADTH_FIRST,StopEvaluator.DEPTH_ONE,ReturnableEvaluator.ALL_BUT_START_NODE,
rel2, dir2).iterator()
while(q2.hasNext)
println(q2.next)
}
}
