A simple visitor of program elements with default behavior appropriate for the RELEASE_8 source version. Visit methods corresponding to RELEASE_8 and earlier language constructs 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.
