```
@PublicSpi
public interface GraphQLSchemaVisitor
```
This visitor interface offers more "smarts" above GraphQLTypeVisitor and aims to be easier to use with more type safe helpers.
You would use it places that need a GraphQLTypeVisitor by doing `new GraphQLSchemaVisitor() { ...}.toTypeVisitor()`
