Example Graph
The following examples run against this graph:
length()
Returns the number of edges in a path.
| Syntax | length(<pathAlias>) |
||
| Arguments | Name | Type | Description |
<pathAlias> |
PATH |
Path alias reference | |
| Return Type | UINT |
||
n().re()[1:3].n() as p
return p{*}, length(p) as length
Result:
| p | length |
|---|---|
 |
2 |
 |
1 |
 |
1 |
pedges()
Collects edges in a path into a list.
| Syntax | pedges(<pathAlias>) |
||
| Arguments | Name | Type | Description |
<pathAlias> |
PATH |
Path alias reference | |
| Return Type | LIST |
||
n({_id == "P1"}).re()[1:2].n() as p
return pedges(p)
Result:
| pedges(p) |
|---|
| [{"from":"P1","to":"P2","uuid":"1","from_uuid":"10448353334522806273","to_uuid":"3098478742654156802","schema":"Cites","values":{}}] |
