Class AbstractElementVisitor6<R,P>

java.lang.Object

javax.lang.model.util.AbstractElementVisitor6<R,P>

Type Parameters:: R - the return type of this visitor's methods. Use Void for visitors that do not need to return results.; P - the type of the additional parameter to this visitor's methods. Use Void for visitors that do not need an additional parameter.

All Implemented Interfaces:: ElementVisitor<R,P>

Direct Known Subclasses:: AbstractElementVisitor7, ElementScanner6, SimpleElementVisitor6

@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.

API Note:

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 and subclasses 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 directly or indirectly 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 a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors.

Since:

1.6

Method Details

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 interface ElementVisitor<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 interface ElementVisitor<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 interface ElementVisitor<R,P>
Implementation Requirements:: The default implementation of this method in AbstractElementVisitor6 will always throw new 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 interface ElementVisitor<R,P>
Implementation Requirements:: Visits a ModuleElement by calling visitUnknown.
Parameters:: e - the element to visit; p - a visitor-specified parameter
Returns:: a visitor-specified result
Since:: 9

visitRecordComponent

public R visitRecordComponent(RecordComponentElement e, P p)

Visits a record component element.

Specified by:: visitRecordComponent in interface ElementVisitor<R,P>
Implementation Requirements:: Visits a RecordComponentElement by calling visitUnknown.
Parameters:: e - the element to visit; p - a visitor-specified parameter
Returns:: a visitor-specified result
Since:: 14
