A visitor of program elements based on their kind with default behavior appropriate for source versions RELEASE_9 through RELEASE_14. For elements Xyz that may have more than one
kind, the visitXyz methods in this class delegate
to the visitXyzAsKind method corresponding to the
first argument's kind.  The visitXyzAsKind methods call defaultAction, passing their arguments to defaultAction's corresponding parameters. 
Type parameters:
<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.
