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.
