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.@SupportedSourceVersion(value=RELEASE_9) public class SimpleElementVisitor9<R,P> extends SimpleElementVisitor8<R,P>
RELEASE_9
source version.
Visit methods corresponding to RELEASE_9
and earlier
language constructs 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 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 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.
