TypeI (Closure Compiler v20170218 API)

All Known Subinterfaces:

FunctionTypeI, ObjectTypeI

All Known Implementing Classes:

AllType, BooleanType, EnumElementType, EnumType, FunctionType, JSType, JSType, NamedType, NoObjectType, NoType, NullType, NumberType, ObjectType, PrototypeObjectType, ProxyObjectType, RecordType, StringType, TemplateType, TemplatizedType, UnionType, UnknownType, VoidType
```
public interface TypeI
```
A common interface for types in the old type system and the new type system, so that the other passes need not know which type system they are using.
