public interface DeclaredType
extends ReferenceType
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.

      Element asElement()
      Returns the element corresponding to this type.
      Returns:
      the element corresponding to this type

    • getEnclosingType

      TypeMirror getEnclosingType()
      Returns the type of the innermost enclosing instance or a NoType of kind NONE if there is no enclosing instance. Only types corresponding to inner classes have an enclosing instance.
      Returns:
      a type mirror for the enclosing type
      See Java Language Specification:
      8.1.3 Inner Classes and Enclosing Instances
      15.9.2 Determining Enclosing Instances

    • getTypeArguments

      List<? extends TypeMirror> getTypeArguments()
      Returns the actual type arguments of this type. For a type nested within a parameterized type (such as Outer<String>.Inner<Number>), only the type arguments of the innermost type are included.
      Returns:
      the actual type arguments of this type, or an empty list if none
