What's the proper way to parse the return type of 'agtype' from the client side?

[rburton]

I see that in the example, I would get the following results based off this query:

SELECT * from cypher('my_graph_name', $$ MATCH p=(a)-[]-(b) RETURN p $$) as (a agtype)

[{"id": 844424930131969, "label": "Part", "properties": {"part_num": "123"}}::vertex, {"id": 1125899906842625, "label": "used_by", "end_id": 844424930131970, "start_id": 844424930131969, "properties": {"quantity": 1}}::edge, {"id": 844424930131970, "label": "Part", "properties": {"part_num": "345"}}::vertex]::path

[{"id": 844424930131970, "label": "Part", "properties": {"part_num": "345"}}::vertex, {"id": 1125899906842625, "label": "used_by", "end_id": 844424930131970, "start_id": 844424930131969, "properties": {"quantity": 1}}::edge, {"id": 844424930131969, "label": "Part", "properties": {"part_num": "123"}}::vertex]::path

Is there a grammar I should be looking for?

I know that basically, Agtype is json format.
but, strictly not same with JSON.

additionally, have annotation like ::path, ::edge, ::vertex.
However, it appears that there is no explanation in the document.

anyway... you can implement with ANTLR4 like behind codes.

Thank you - this is great!
