@SupportedSourceVersion(RELEASE_6) public abstract class AbstractElementVisitor6<R,P> extends Object implements ElementVisitor<R,P>
A skeletal visitor of program elements with default behavior appropriate for theRELEASE_6
source version.WARNING: The
ElementVisitor
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 element 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:

Method Detail
visit
public final R visit(Element e, P p)
Visits any program element as if by passing itself to that element'saccept
method. The invocationv.visit(elem, p)
is equivalent toelem.accept(v, p)
.- Specified by:
visit
in interfaceElementVisitor<R,P>
- Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
visit
public final R visit(Element e)
Visits any program element as if by passing itself to that element'saccept
method and passingnull
for the additional parameter. The invocationv.visit(elem)
is equivalent toelem.accept(v, null)
.- Specified by:
visit
in interfaceElementVisitor<R,P>
- Parameters:
e
- the element to visit- Returns:
- a visitor-specified result
visitUnknown
public R visitUnknown(Element e, P p)
Visits an unknown kind of element. This can occur if the language evolves and new kinds of elements are added to theElement
hierarchy.- Specified by:
visitUnknown
in interfaceElementVisitor<R,P>
- Implementation Requirements:
- The default implementation of this method in
AbstractElementVisitor6
will always thrownew UnknownElementException(e, p)
. This behavior is not required of a subclass. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
- Throws:
UnknownElementException
- a visitor implementation may optionally throw this exception
visitModule
public R visitModule(ModuleElement e, P p)
Visits a module element.- Specified by:
visitModule
in interfaceElementVisitor<R,P>
- Implementation Requirements:
- Visits a
ModuleElement
by callingvisitUnknown
. - Parameters:
e
- the element to visitp
- a visitor-specified parameter- Returns:
- a visitor-specified result
- Since:
- 9
