basically
Node pizza =
gdb.findByLabelAndProperty("Thing","name","Pizza").iterator().next();
Node iceCream = gdb.findByLabelAndProperty("Thing","name","Ice
Cream").iterator().next();
for (Relationship rel : pizza.getRelationships(Direction.INCOMING, Type.LIKES) {
Node person = rel.getStartNode();
if (connected(person,iceCream,Type.LIKES) result.add(person);
}
public boolean connected(Node from, Node to, RelationshipType type) {
for (Relationship rel : from.getRelationships(Direction.OUTGOING, type) {
if (rel.getEndNode().equals(to)) return true;
}
return false;
}
2) you can also collect person-nodes from both like's into a Set each and then
use set1.retailAll(set2)
3) you can also iterate over all people and check if the end-nodes of their
likes relationships are pizza AND ice-cream and if both then add them to the
result
