    void

    Creates the error/warning message that we need to show users/IDEs when ANTLR has found a parsing error, has recovered from it and is now telling us that a parsing exception occurred.

      protected AbstractParser(org.antlr.runtime.TokenStream input, org.antlr.runtime.RecognizerSharedState state)
      Create a new parser instance, pre-supplying the input token stream and the shared state.

      This is only used when a grammar is imported into another grammar, but we must supply this constructor to satisfy the super class contract.

      Parameters:
      input - The stream of tokesn that will be pulled from the lexer
      state - The shared state object created by an interconnectd grammar

    • displayRecognitionError

      public void displayRecognitionError(String[] tokenNames, org.antlr.runtime.RecognitionException e)
      Creates the error/warning message that we need to show users/IDEs when ANTLR has found a parsing error, has recovered from it and is now telling us that a parsing exception occurred.
      Overrides:
      displayRecognitionError in class org.antlr.runtime.BaseRecognizer
      Parameters:
      tokenNames - token names as known by ANTLR (which we ignore)
      e - The exception that was thrown
