Interface DeclaredType

All Superinterfaces:: AnnotatedConstruct, 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.

Method Details

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 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
