Examples of javax.lang.model.type.DeclaredType

javax.lang.model.type.DeclaredType
Represents a declared type, either a class type or an interface type. This includes parameterized types such as {@code java.util.Set}as well as raw types.
While a {@code TypeElement} represents a class or interfaceelement, a {@code DeclaredType} represents a classor interface type, the latter being a use (or invocation) of the former. See {@link TypeElement} for more on this distinction.
The supertypes (both class and interface types) of a declared type may be found using the {@link Types#directSupertypes(TypeMirror)} method. This returns thesupertypes with any type arguments substituted in. @author Joseph D. Darcy @author Scott Seligman @author Peter von der Ahé @see TypeElement @since 1.6
