How to get Only Unique node in Neo4j Query

I scanned a small java application and now I'm trying to run this query on neo4J

MATCH (n:Class)-[rel]-(cls:Class) RETURN n,cls,rel

the result is giving multiple nodes with the same id is there any way to get all these relations but each unique node should come once only. I did manage to get only unique through the loop but is there any way through this query itself will give unique node

If you want to return a node and edge array, I would suggest the following cypher query:

MATCH (n:Class)
WITH collect(n) as nodeArray
MATCH (c1:Class)-[rel]->(c2:Class)
WITH nodeArray, collect([c1,rel,c2]) as edgeArray
RETURN nodeArray, edgeArray

You could obviously construct the edgeArray differently, but I don't know what is your preferred structure.
