- Classes in org.apache.tinkerpop.gremlin.structure.io used by org.apache.tinkerpop.gremlin.structure
  Class and Description
  Io Ties together the core interfaces of an IO format: `GraphReader`, `GraphWriter` and `Mapper`.
  Io.Builder Helps to construct an `Io` implementation and should be implemented by every such implementation as that class will be passed to `Graph.io(Io.Builder)` by the user.

- Classes in org.apache.tinkerpop.gremlin.structure.io used by org.apache.tinkerpop.gremlin.structure.io
  Class and Description
  GraphReader Functions for reading a graph and its graph elements from a different serialization format.
  GraphReader.ReaderBuilder Largely a marker interface for builder classes that construct a `GraphReader`.
  GraphWriter Functions for writing a graph and its elements to a serialized format.
  GraphWriter.WriterBuilder Largely a marker interface for builder classes that construct a `GraphWriter`.

  Io.Builder Helps to construct an `Io` implementation and should be implemented by every such implementation as that class will be passed to `Graph.io(Io.Builder)` by the user.
  IoRegistry A generalized custom serializer registry for providers implementing a `Graph`.
  Mapper.Builder Largely a marker interface for builders that construct `Mapper` instances.
