TypeName

Any type in Swift's type system. This class identifies simple types like Int and String, composite types like Optional<String> and Set<String>, and unassignable types like Void.

Type names are dumb identifiers only and do not model the values they name. For example, the type name for Swift.Array doesn't know about the count property, the fact that arrays are collections, or even that it accepts a single type parameter.

Instances of this class are immutable value objects that implement equals() and hashCode() properly.

Defining new types

Create new reference types like MyModule.HelloWorld with DeclaredTypeName.typeName. To build composite types like Set<Long>, use the factory methods on ParameterizedTypeName and TypeVariableName.
