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 AbstractElementVisitor6<R,P> extends Object implements ElementVisitor<R,P>
A skeletal visitor of program elements with default behavior appropriate for the RELEASE_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.

Method Detail
visit
public final R visit(Element e, P p)
Visits any program element as if by passing itself to that element's accept
method. The invocation v.visit(elem, p)
is equivalent to elem.accept(v,
p)
.
- Specified by:
-
visit
in interfaceElementVisitor<R,P>
- Parameters:
-
e
- the element to visit -
p
- 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's accept
method and passing null
for the additional parameter. The invocation v.visit(elem)
is equivalent to elem.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 the Element
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 visit -
p
- 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 visit -
p
- a visitor-specified parameter - Returns:
- a visitor-specified result
