Class GryoWriter

java.lang.Object

org.apache.tinkerpop.gremlin.structure.io.gryo.GryoWriter

All Implemented Interfaces:

GraphWriter

public class GryoWriter
extends Object
implements GraphWriter

The GraphWriter for the Gremlin Structure serialization format based on Kryo. The format is meant to be non-lossy in terms of Gremlin Structure to Gremlin Structure migrations (assuming both structure implementations support the same graph features).

                throws IOException

Description copied from interface: GraphWriter

Write the entire graph to a stream.

Specified by:

writeGraph in interface GraphWriter

Throws:

IOException

writeVertex

public void writeVertex(OutputStream outputStream,
                        Vertex v,
