    29  * A visitor of trees, in the style of the visitor design pattern.

    30  * Classes implementing this interface are used to operate

    31  * on a tree when the kind of tree is unknown at compile time.

    32  * When a visitor is passed to an tree's {@link Tree#accept

    33  * accept} method, the <tt>visit<i>XYZ</i></tt> method most applicable

    34  * to that tree is invoked.

    35  *

    36  * <p> Classes implementing this interface may or may not throw a

    37  * {@code NullPointerException} if the additional parameter {@code p}

    38  * is {@code null}; see documentation of the implementing class for

    39  * details.

    40  *

    41  * <p> <b>WARNING:</b> It is possible that methods will be added to

    42  * this interface to accommodate new, currently unknown, language

    43  * structures added to future versions of the Java&trade; programming

    44  * language.  Therefore, visitor classes directly implementing this

    45  * interface may be source incompatible with future versions of the

    46  * platform.

    47  *

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

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

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

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

    52  *            additional parameter.
