Just a heads up here:
if (r.getType().equals(rel.getType()))
isn't accurate. If you read the javadocs you can see that you cannot compare
RelationshipType instances, but rather their names or use the short-hand
method on Relationship:
if (r.isType(rel.getType()))

Hello there!
First of all, thanks for the help in all my previous questions, all the
answers have been helping me to use Neo4j with success.
I have a very simple question, but I haven't found the answer yet...
I'd like to have a function, which signature would be more or less like
this:
Bruno,
There is no such function low level, but toy can use a Shortest path algo to
check this. What is the maximum length for a path between the nodes?

Easy: just one.
For now, I've written this, but I'm still not sure it is the simplest
way to write it
public boolean areConnected(Node n1,Node n2,Relationship
rel,Direction dir) throws Exception {
IterableRelationship relationships = n1.getRelationships(dir);

There is one caveat to this method, you'd have to know which node is most
densely connected.
Suppose one of the nodes has 100,000 relationships
().equals(n2)
return true;
else if (rel2.getEndNode().equals(n1))
return true;
}
return false;
}

You know me and my obsession for densely connected nodes :-)

Good catch Niels, thanks - my brain is in jet lag mode
