@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_6source version.WARNING: The
ElementVisitorinterface 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
visitUnknownmethod. 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'sacceptmethod. The invocationv.visit(elem, p)is equivalent toelem.accept(v, p).- Specified by:
visitin 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'sacceptmethod and passingnullfor the additional parameter. The invocationv.visit(elem)is equivalent toelem.accept(v, null).- Specified by:
visitin 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 theElementhierarchy.- Specified by:
visitUnknownin interfaceElementVisitor<R,P>- Implementation Requirements:
- The default implementation of this method in
AbstractElementVisitor6will 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:
visitModulein interfaceElementVisitor<R,P>- Implementation Requirements:
- Visits a
ModuleElementby callingvisitUnknown. - Parameters:
e- the element to visitp- a visitor-specified parameter- Returns:
- a visitor-specified result
