[jira] [Created] (TINKERPOP-2419) Gremlin.Net does not fully implement GraphSON serialization

Shaun created TINKERPOP-2419:
--------------------------------

             Summary: Gremlin.Net does not fully implement GraphSON serialization
                 Key: TINKERPOP-2419
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2419
             Project: TinkerPop
          Issue Type: Bug
          Components: dotnet
    Affects Versions: 3.4.8
            Reporter: Shaun


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?
