    34  * A skeletal visitor of program elements with default behavior

    35  * appropriate for the {@link SourceVersion#RELEASE_7 RELEASE_7}

    36  * source version.

    37  *

    38  * <p> <b>WARNING:</b> The {@code ElementVisitor} interface

    39  * implemented by this class may have methods added to it in the

    40  * future to accommodate new, currently unknown, language structures

    41  * added to future versions of the Java&trade; programming language.

    42  * Therefore, methods whose names begin with {@code "visit"} may be

    43  * added to this class in the future; to avoid incompatibilities,

    44  * classes which extend this class should not declare any instance

    45  * methods with names beginning with {@code "visit"}.

    46  *

    47  * <p>When such a new visit method is added, the default

    48  * implementation in this class will be to call the {@link

    49  * #visitUnknown visitUnknown} method.  A new abstract element visitor

    50  * class will also be introduced to correspond to the new language

    51  * level; this visitor will have different default behavior for the

    52  * visit method in question.  When the new visitor is introduced, all

    53  * or portions of this visitor may be deprecated.

    54  *

    55  * <p>Note that adding a default implementation of a new visit method

    56  * in a visitor class will occur instead of adding a <em>default

    57  * method</em> directly in the visitor interface since a Java SE 8

    58  * language feature cannot be used to this version of the API since

    59  * this version is required to be runnable on Java SE 7

    60  * implementations.  Future versions of the API that are only required

    61  * to run on Java SE 8 and later may take advantage of default methods

    62  * in this situation.

    63  *

    64  * @param <R> the return type of this visitor's methods.  Use {@link

    65  *            Void} for visitors that do not need to return results.

    66  * @param <P> the type of the additional parameter to this visitor's

    67  *            methods.  Use {@code Void} for visitors that do not need an

    68  *            additional parameter.

    69  *

    70  * @see AbstractElementVisitor6

    71  * @see AbstractElementVisitor8

    72  * @since 1.7
