@SupportedSourceVersion(RELEASE_6) public abstract class AbstractTypeVisitor6<R,P> extends Object implements TypeVisitor<R,P>
A skeletal visitor of types with default behavior appropriate for theRELEASE_6
source version.WARNING: The
TypeVisitor
interface implemented by this class may have methods added to it in the future to accommodate new, currently unknown, language structures added to future versions of the Java™ programming language. Therefore, methods whose names begin with"visit"
may be added to this class in the future; to avoid incompatibilities, classes which extend this class should not declare any instance methods with names beginning with"visit"
.When such a new visit method is added, the default implementation in this class will be to call the
visitUnknown
method. A new abstract type visitor class will also be introduced to correspond to the new language level; this visitor will have different default behavior for the visit method in question. When the new visitor is introduced, all or portions of this visitor may be deprecated.- Since:
- 1.6

Method Detail
visit
public final R visit(TypeMirror t, P p)
Visits any type mirror as if by passing itself to that type mirror'saccept
method. The invocationv.visit(t, p)
is equivalent tot.accept(v, p)
.- Specified by:
visit
in interfaceTypeVisitor<R,P>
- Parameters:
t
- the type to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
visit
public final R visit(TypeMirror t)
Visits any type mirror as if by passing itself to that type mirror'saccept
method and passingnull
for the additional parameter. The invocationv.visit(t)
is equivalent tot.accept(v, null)
.- Specified by:
visit
in interfaceTypeVisitor<R,P>
- Parameters:
t
- the type to visit- Returns:
- a visitor-specified result
visitUnion
public R visitUnion(UnionType t, P p)
Visits a union type.- Specified by:
visitUnion
in interfaceTypeVisitor<R,P>
- Implementation Requirements:
- Visits a
UnionType
element by callingvisitUnknown
. - Parameters:
t
- the type to visitp
- a visitor-specified parameter- Returns:
- the result of
visitUnknown
- Since:
- 1.7
visitIntersection
public R visitIntersection(IntersectionType t, P p)
Visits an intersection type.- Specified by:
visitIntersection
in interfaceTypeVisitor<R,P>
- Implementation Requirements:
- Visits an
IntersectionType
element by callingvisitUnknown
. - Parameters:
t
- the type to visitp
- a visitor-specified parameter- Returns:
- the result of
visitUnknown
- Since:
- 1.8
visitUnknown
public R visitUnknown(TypeMirror t, P p)
Visits an unknown kind of type. This can occur if the language evolves and new kinds of types are added to theTypeMirror
hierarchy.- Specified by:
visitUnknown
in interfaceTypeVisitor<R,P>
- Implementation Requirements:
- The default implementation of this method in
AbstractTypeVisitor6
will always thrownew UnknownTypeException(t, p)
. This behavior is not required of a subclass. - Parameters:
t
- the type to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
- Throws:
UnknownTypeException
- a visitor implementation may optionally throw this exception
