Represents a declared type, either a class type or an interface type. This includes parameterized types such as java.util.Set<String> as well as raw types.

While a TypeElement represents a class or interface element, a DeclaredType represents a class or interface type, the latter being a use (or invocation) of the former. See TypeElement for more on this distinction.

The supertypes (both class and interface types) of a declared type may be found using the Types.directSupertypes(TypeMirror) method. This returns the supertypes with any type arguments substituted in.
