  • Method Details

    • getTokenNames

      @Deprecated public String[] getTokenNames()
      Deprecated.
      Overrides:
      getTokenNames in class org.projectnessie.shaded.org.antlr.v4.runtime.Lexer

    • getVocabulary

      public org.projectnessie.shaded.org.antlr.v4.runtime.Vocabulary getVocabulary()
      Overrides:
      getVocabulary in class org.projectnessie.shaded.org.antlr.v4.runtime.Recognizer<Integer,org.projectnessie.shaded.org.antlr.v4.runtime.atn.LexerATNSimulator>

    • isValidDecimal

      public boolean isValidDecimal()
      Verify whether current token is a valid decimal token (which contains dot). Returns true if the character that follows the token is not a digit or letter or underscore. For example: For char stream "2.3", "2." is not a valid decimal token, because it is followed by digit '3'. For char stream "2.3_", "2.3" is not a valid decimal token, because it is followed by '_'. For char stream "2.3W", "2.3" is not a valid decimal token, because it is followed by 'W'. For char stream "12.0D 34.E2+0.12 " 12.0D is a valid decimal token because it is followed by a space. 34.E2 is a valid decimal token because it is followed by symbol '+' which is not a digit or letter or underscore.

    • isHint

      public boolean isHint()
      This method will be called when we see '/*' and try to match it as a bracketed comment. If the next character is '+', it should be parsed as hint later, and we cannot match it as a bracketed comment. Returns true if the next character is '+'.
