Example Usage
The example below will help us learn how to use this procedure.
The following creates a graph containing two nodes connected by a relationship:
CREATE path=(c:Car {make:"Volvo"})-[rel:DRIVES {year:2001}]->(p:Person {name:"Dan"}) RETURN path
The following inverts the direction of the relationship:
MATCH (c:Car)-[rel:DRIVES]->(p:Person)
CALL apoc.refactor.invert(rel)
yield input, output
RETURN input, output
input | output |
---|---|
2 |
{"identity":3,"start":9,"end":8,"type":"DRIVES","properties":{"year":2001}} |
If we execute MATCH path=(c:Car {make:"Volvo"})-[rel:DRIVES {year:2001}]-(p:Person {name:"Dan"}) RETURN path
,
it will result in the following graph:
