- javax.lang.model.util.AbstractTypeVisitor6<R,P>
- Type Parameters:
-
R
- the return type of this visitor's methods. UseVoid
for visitors that do not need to return results. -
P
- the type of the additional parameter to this visitor's methods. UseVoid
for visitors that do not need an additional parameter.

@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 the RELEASE_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.

Method Detail
visit
public final R visit(TypeMirror t, P p)
Visits any type mirror as if by passing itself to that type mirror's accept
method. The invocation v.visit(t, p)
is equivalent to
t.accept(v, p)
.
- Specified by:
-
visit
in interfaceTypeVisitor<R,P>
- Parameters:
-
t
- the type to visit -
p
- 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's accept
method and passing null
for the additional parameter. The invocation v.visit(t)
is equivalent to t.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 visit -
p
- 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 visit -
p
- 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 the TypeMirror
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 visit -
p
- a visitor-specified parameter - Returns:
- a visitor-specified result
- Throws:
-
UnknownTypeException
- a visitor implementation may optionally throw this exception
