Hi,
I am trying to traverse documents where the links are part of list of maps
and restrict the traversal based on map attributes
I tried to construct a simple setup to demonstrate the problem:
create class term
insert into term(id) values (1)
insert into term(id) values (2)
insert into term(id) values (3)
insert into term(id) values (4)
update #11:2 set xrefs=[ {"type" : "is_a" , "target" : #11:3 }, {"type" :
"binds", "target" : #11:1 } ]
the result would be
----+-----+----+-----
# |@RID |id |xrefs
----+-----+----+-----
0 |#11:0|1 |null
1 |#11:1|2 |null
2 |#11:2|3 |[2]
3 |#11:3|4 |null
----+-----+----+-----
the class term contains a list of maps called xrefs. Every map entry
contains a "type" (string) and a "target" (link)
My goal is to traverse the chain of xrefs of term documents where I
constrain the path to certain value of the "type" key in the xrefs map.
I have started with
traverse xrefs['target'] from #11:2
----+-----+-----+----
# |@RID |xrefs|id
----+-----+-----+----
0 |#11:2|[2] |3
1 |#11:1|null |2
2 |#11:3|null |4
----+-----+-----+----
and experimented with while and the context variables but so far I have
failed to address the map entry - $current is the whole document in the
path I assume.
Has anybody an Idea how this traverse should look like?
