/**
* A simple visitor of program elements with default behavior
* appropriate for the {@link SourceVersion#RELEASE_7 RELEASE_7}
* source version.
*
* Visit methods corresponding to {@code RELEASE_7} and earlier
* language constructs call {@link #defaultAction defaultAction},
* passing their arguments to {@code defaultAction}'s corresponding
* parameters.
*
* <p> Methods in this class may be overridden subject to their
* general contract. Note that annotating methods in concrete
* subclasses with {@link java.lang.Override @Override} will help
* ensure that methods are overridden as intended.
*
* <p> <b>WARNING:</b> The {@code 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 {@code "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 {@code "visit"}.
*
* <p>When such a new visit method is added, the default
* implementation in this class will be to call the {@link
* #visitUnknown 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.
*
* @param <R> the return type of this visitor's methods. Use {@code Void}
* for visitors that do not need to return results.
* @param <P> the type of the additional parameter to this visitor's methods. Use {@code Void}
* for visitors that do not need an additional parameter.
*
* @see SimpleElementVisitor6
* @since 1.7
