Class GryoIo

java.lang.Object

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

All Implemented Interfaces:

Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

public final class GryoIo
extends Object
implements Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

Constructs Gryo IO implementations given a Graph and IoRegistry. Implementers of the Graph interfaces should see the GryoMapper for information on the expectations for the IoRegistry.

Method Detail

reader

public GryoReader.Builder reader()

Creates a GraphReader.ReaderBuilder implementation . Implementers should call the Io.mapper() function to feed its result to the builder. In this way, custom class serializers registered to the Mapper.Builder by Graph implementations will end up being used for the serialization process.

Specified by:

reader in interface Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

writer

public GryoWriter.Builder writer()

Creates a GraphWriter.WriterBuilder implementation . Implementers should call the Io.mapper() function to feed its result to the builder. In this way, custom class serializers registered to the Mapper.Builder by Graph implementations will end up being used for the serialization process.

Specified by:

writer in interface Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

mapper

public GryoMapper.Builder mapper()

Constructs a Mapper.Builder which is responsible for constructing the abstraction over different serialization methods. Implementations should set defaults as required, but most importantly need to make the appropriate call to Mapper.Builder.addRegistry(IoRegistry) which will provide the builder with any required custom serializers of the Graph.

Specified by:

mapper in interface Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

writeGraph

public void writeGraph(String file)
                throws IOException

Write a Graph to file using the default configuration of the Io.writer() and its supplied Io.mapper().

Specified by:

writeGraph in interface Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

Throws:

IOException

readGraph

public void readGraph(String file)
               throws IOException

Read a Graph from file using the default configuration of the Io.reader() and its supplied Io.mapper().

Specified by:

readGraph in interface Io<GryoReader.Builder,GryoWriter.Builder,GryoMapper.Builder>

Throws:

IOException

build

public static Io.Builder<GryoIo> build()

Create a new builder using the default version of Gryo - v3.

build

public static Io.Builder<GryoIo> build(GryoVersion version)

Create a new builder using the specified version of Gryo.
