Io.Builder (Apache TinkerPop 3.6.6 API)

Enclosing interface:

Io<R extends GraphReader.ReaderBuilder,W extends GraphWriter.WriterBuilder,M extends Mapper.Builder>
```
public static interface Io.Builder<I extends Io>
```
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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`I`	`create()`	Providers call this method in the `Graph.io(Io.Builder)` method to construct the `Io` instance and return the value.
`Io.Builder<? extends Io>`	`graph(Graph g)`	Providers use this method to supply the current instance of their `Graph` to the builder.
`Io.Builder<? extends Io>`	`onMapper(Consumer<Mapper.Builder> onMapper)`	Allows a `Graph` implementation to have full control over the `Mapper.Builder` instance.
`<V> boolean`	`requiresVersion(V version)`	Determines if the version matches the one configured for this builder.

- Method Detail
  - onMapper
```
Io.Builder<? extends Io> onMapper(Consumer<Mapper.Builder> onMapper)
```
    Allows a Graph implementation to have full control over the Mapper.Builder instance. Typically, the implementation will just pass in its IoRegistry implementation so that the Mapper that gets built will have knowledge of any custom classes and serializers it may have.
    End-users should not use this method directly. If a user wants to register custom serializers, then such things can be done via calls to Io.mapper() after the Io is constructed via Graph.io(Io.Builder).
  - graph
```
Io.Builder<? extends Io> graph(Graph g)
```
    Providers use this method to supply the current instance of their Graph to the builder. End-users should not call this method directly.
  - requiresVersion
```
<V> boolean requiresVersion(V version)
```
    Determines if the version matches the one configured for this builder. Graph providers can use this in calls to Graph.io(Builder) to figure out the correct versions of registries to add.
  - create
```
I create()
```
    Providers call this method in the Graph.io(Io.Builder) method to construct the Io instance and return the value. End-users will typically not call this method.
