 They are responsible for:
 
- - mapping scalar types (for instance mapping the "int" PHP type to GraphQL Integer type)
- - detecting nullable/non-nullable types (for instance interpreting "?int" or "int|null")
- - mapping list types (mapping a PHP array to a GraphQL list)
- - mapping union types
- - mapping enums

+- detecting nullable/non-nullable types (for instance interpreting "?int" or "int|null")
+- mapping list types (mapping a PHP array to a GraphQL list)
+- mapping union types

 Root type mappers have access to the *context* of a type: they can access the PHP DocBlock and read annotations.
 If you want to write a custom type mapper that needs access to annotations, it needs to be a "root type mapper".
 
 GraphQLite provides 6 classes implementing `RootTypeMapperInterface`:
 
- - `NullableTypeMapperAdapter`: a type mapper in charge of making GraphQL types non-nullable if the PHP type is non-nullable
- - `CompoundTypeMapper`: a type mapper in charge of union types
- - `IteratorTypeMapper`: a type mapper in charge of iterable types (for instance: `MyIterator|User[]`)
- - `MyCLabsEnumTypeMapper`: maps MyCLabs/enum types to GraphQL enum types
- - `BaseTypeMapper`: maps scalar types and lists. Passes the control to the "recursive type mappers" if an object is encountered.
- - `FinalRootTypeMapper`: the last type mapper of the chain, used to throw error if no other type mapper managed to handle the type.

- - `GlobTypeMapper`: scans classes in a directory for the `@Type` or `@ExtendType` annotation and maps those to GraphQL types
