Interface DeclaredType
- All Superinterfaces:
- ReferenceType, TypeMirror
- All Known Subinterfaces:
- ErrorType
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.
This interface is also used to represent intersection types.
An intersection type is implicit in a program rather than being
explictly declared. For example, the bound of the type parameter
<T extends Number & Runnable>
is an intersection type. It is represented by a DeclaredType
with Number as its superclass and Runnable as its
lone superinterface.

TypeElement
asElement
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 The Java Language Specification, Third Edition:
- 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
