Functions

func NewDb

func NewDb(name string, options map[string][]string) (DatabaseService, error)

NewDb creates a DB instance of a simple memory backed graph DB

Example

db, _ := NewDb("test", nil)

nodeA := db.NewNode()
nodeA.SetProperty("foo", "bar")

nodeB := db.NewNode()

fmt.Println("nodes: ", nodeA, nodeB)

relAB := nodeA.RelateTo(nodeB, "BELONGS_TO")

fmt.Println("relation: ", relAB)

path := db.FindPath(nodeA, nodeB)

fmt.Println("path: ", path)

nodeC := db.NewNode("A")

nodeB.RelateTo(nodeC, "BELONGS_TO")

path = db.FindPath(nodeA, nodeC)

fmt.Println("path: ", path)

Output:

nodes:  (0 {foo:"bar",}) (1)
relation:  (0 {foo:"bar",})-[:BELONGS_TO]->(1)
path:  (0 {foo:"bar",})-[:BELONGS_TO]->(1)
path:  (0 {foo:"bar",})-[:BELONGS_TO]->(1)-[:BELONGS_TO]->(2:A)
