---------------------------------------
Resolution: Implemented
> GraphSON writeGraph not producing valid json object
> ---------------------------------------------------
>
> Key: TINKERPOP3-699
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-699
> Project: TinkerPop 3
> Issue Type: Improvement
> Components: io
> Affects Versions: 3.0.0-incubating
> Reporter: Jim Lloyd
> Assignee: stephen mallette
> Fix For: 3.0.1-incubating
>
>
> The following code in the M9-rc3 console produces an incorrect t.json file:
> gremlin> graph = TinkerFactory.createModern()
> ==>tinkergraph[vertices:6 edges:6]
> gremlin> g = graph.traversal()
> ==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
> gremlin> f = new FileOutputStream("t.json")
> ==>java.io.FileOutputStream@7927bd9f
> gremlin> mapper =
> graph.io(IoCore.graphson()).mapper().embedTypes(true).create()
> ==>org.apache.tinkerpop.gremlin.structure.io.graphson.GraphSONMapper@63f34b70
> gremlin>
> graph.io(IoCore.graphson()).writer().mapper(mapper).create().writeGraph(f,
> graph)
> ==>null
> gremlin> f.close()
> ==>null
> The file is a stream of independent vertices rather than a single json object
> following the GraphSON schema. I.e. the output looks like the this:
> {"id":1,"label":"person", ... }
> {"id":2,"label":"person", ... }
> {"id":3,"label":"software", ... }
> Where ... represents omitted fields.
> A separate issue but related issue is that the documentation examples use
> "CoreIo" but the actual name of that class is "IoCore", as shown in the
> console session above.
