Stephen Mallette updated TINKERPOP-2419:
----------------------------------------
Issue Type: Improvement (was: Bug)
> Gremlin.Net does not fully implement GraphSON serialization
> -----------------------------------------------------------
>
> Key: TINKERPOP-2419
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2419
> Project: TinkerPop
> Issue Type: Improvement
> Components: dotnet
> Affects Versions: 3.4.8
> Reporter: Shaun
> Priority: Major
>
> Quite a bit of Gremlin.Net.Structure.* seems to not be implemented:
> * Gremlin.Net.Structure.Graph doesn't actually provide any collections for
> Edge, Vertices, or VertexProperties
> * Gremlin.Net.Structure.IO.GraphSON.GraphSONWriter (and derived
> GraphSON2Writer/GraphSON3Writer) is missing writeGraph
> * Gremlin.Net.Structure.IO.GraphSON.GraphSONReader (and derived
> GraphSON2Reader/GraphSON3Reader) is missing readGraph
> The combination of the above means the Gremlin.Net library can't be used to
> serialize GraphSON (of any version).
>
> I can get partial GraphSON (missing all VertexProperties) with:
> {code:c#}
> List<Vertex> Vertices = new List<Vertex>();
> List<VertexProperty> VertexProperties = new List<VertexProperty>();
> List<Edge> Edges = new List<Edge>();
> /* build up collections */
> var sb = new StringBuilder();
> var gsWriter = new GraphSON3Writer();
> // NOTE: There is supposed to be a .writeGraph method on GraphSON3Writer, but
> there isn't 😣
> sb.AppendLine("{");
> sb.AppendLine(" \"mode\":\"EXTENDED\",");
> sb.AppendLine(" \"vertices\": [");
> // Unique vertices by name
> foreach (var v in state.Vertices)
> {
> sb.AppendLine(gsWriter.WriteObject(v));
> }
> sb.AppendLine(" ],");
> sb.AppendLine(" \"edges\": [");
> // Unique edges by name
> foreach (var e in state.Edges)
> {
> sb.AppendLine(gsWriter.WriteObject(e));
> }
> sb.AppendLine(" ]");
> sb.AppendLine("}");
> var brokenGraphSON = sb.ToString();
> {code}
>
> Am I missing something obvious here?
