@SupportedSourceVersion(RELEASE_6) public class SimpleElementVisitor6<R,P> extends AbstractElementVisitor6<R,P>
A simple visitor of program elements with default behavior appropriate for theRELEASE_6source version. Visit methods corresponding toRELEASE_6language constructs calldefaultAction, passing their arguments todefaultAction's corresponding parameters. For constructs introduced inRELEASE_7and later,visitUnknownis called instead.Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with
@Overridewill help ensure that methods are overridden as intended.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 simple 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
-
defaultAction
protected R defaultAction(Element e, P p)
The default action for visit methods.- Implementation Requirements:
- The implementation in this class just returns
DEFAULT_VALUE; subclasses will commonly override this method. - Parameters:
e- the element to processp- a visitor-specified parameter- Returns:
DEFAULT_VALUEunless overridden
-
visitPackage
public R visitPackage(PackageElement e, P p)
Visits a package element.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:
e- the element to visitp- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitType
public R visitType(TypeElement e, P p)
Visits a type element.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:
e- the element to visitp- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitVariable
public R visitVariable(VariableElement e, P p)
Visits a variable element.- Implementation Requirements:
- This implementation calls
defaultAction, unless the element is aRESOURCE_VARIABLEin which casevisitUnknownis called. - Parameters:
e- the element to visitp- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitExecutable
public R visitExecutable(ExecutableElement e, P p)
Visits an executable element.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:
e- the element to visitp- a visitor-specified parameter- Returns:
- a visitor-specified result
-
visitTypeParameter
public R visitTypeParameter(TypeParameterElement e, P p)
Visits a type parameter element.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:
e- the element to visitp- a visitor-specified parameter- Returns:
- a visitor-specified result
