      Specified by:
      visitTerminal in interface org.antlr.v4.runtime.tree.ParseTreeListener
      Parameters:
      node - the terminal node being entered

      Parameters:
      node - the error node being visited

    • exitEveryRule

      public void exitEveryRule(org.antlr.v4.runtime.ParserRuleContext ctx)
      Called when exiting any parser rule in the parse tree. Checks for cancellation and reports progress when exiting rules at or above monitoring level.
      Specified by:
      exitEveryRule in interface org.antlr.v4.runtime.tree.ParseTreeListener
      Parameters:
      ctx - the parser rule context being exited
