    024 * Sanitizer is an interface to be used in conjunction with {@link PropertySanitizer}.
    025 * <p/>
    026 * The Sanitizer implementation has the option to provide a different value for each level of
    027 * {@link cascading.management.annotation.Visibility}.
    028 * <p/>
    029 * For example, if the raw value is an URL, the {@code PUBLIC} sanitized value may just include the URL path. The
    030 * {@code PROTECTED} value may retain the query string, and the {@code PRIVATE} value may retain the scheme and
    031 * domain name of the server.
    032 * <p/>
    033 * If a Sanitizer returns {@code null}, no value will be available for that requested visibility.
    034 * <p/>
    035 * Implementations of this interface must provide a default no-args Constructor.
