A visitor of program elements based on their
kind with default behavior appropriate for source versions
RELEASE_9
through
RELEASE_12
. For
elementsXyz
that may have more than one kind, the
visitXyz
methods in this class delegate to the
visitXyzAsKind
method corresponding to the first argument's kind. The
visitXyzAsKind
methods call
defaultAction
, passing their arguments to
defaultAction
's corresponding parameters.
Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with @Override
will help ensure that methods are overridden as intended.
WARNING: The ElementVisitor
interface implemented by this class may have methods added to it or the ElementKind
enum
used in this case may have constants 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 kind 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.
