    • getCurrentIdentifierSource

      public char[] getCurrentIdentifierSource()

    • getCurrentTokenEndPosition

      public int getCurrentTokenEndPosition()
      Description copied from interface: IScanner
      Answers the ending position of the current token inside the original source. This position is zero-based and inclusive. It corresponds to the position of the last character which is part of this token. If this character was a unicode escape sequence, it points at the last character of this sequence.
      Specified by:
      getCurrentTokenEndPosition in interface IScanner
      Returns:
      the ending position of the current token inside the original source

    • getCurrentTokenSource

      public char[] getCurrentTokenSource()
      Description copied from interface: IScanner
      Answers the current identifier source, after unicode escape sequences have been translated into unicode characters. For example, if original source was \\u0061bc then it will answer abc.
      Specified by:
      getCurrentTokenSource in interface IScanner
      Returns:
      the current identifier source, after unicode escape sequences have been translated into unicode characters

    • getCurrentTokenString

      Description copied from interface: IScanner
      Answers the current identifier source, before unicode escape sequences have been translated into unicode characters. For example, if original source was \\u0061bc then it will answer \\u0061bc.
      Specified by:
      getRawTokenSource in interface IScanner
      Returns:
      the current identifier source, before unicode escape sequences have been translated into unicode characters

    • getCurrentTokenStartPosition

      public int getCurrentTokenStartPosition()
      Description copied from interface: IScanner
      Answers the starting position of the current token inside the original source. This position is zero-based and inclusive. It corresponds to the position of the first character which is part of this token. If this character was a unicode escape sequence, it points at the first character of this sequence.
      Specified by:
      getCurrentTokenStartPosition in interface IScanner
      Returns:
      the starting position of the current token inside the original source

    • getLineEnd

      public final int getLineEnd(int lineNumber)
      Description copied from interface: IScanner
      Answers the ending position of a given line number. This line has to have been encountered already in the tokenization process (in other words, it cannot be used to compute positions of lines beyond current token). Once the entire source has been processed, it can be used without any limit. Line ending positions are zero-based, and correspond to the last character of the line separator (in case multi-character line separators).
      Specified by:
      getLineEnd in interface IScanner
      Parameters:
      lineNumber - the given line number
      Returns:
      the ending position of a given line number

    • getLineEnds

      public final int[] getLineEnds()
      Description copied from interface: IScanner
      Answers an array of the ending positions of the lines encountered so far. Line ending positions are zero-based, and correspond to the last character of the line separator (in case multi-character line separators).
      Specified by:
      getLineEnds in interface IScanner
      Returns:
      an array of the ending positions of the lines encountered so far

    • getLineStart

      public final int getLineStart(int lineNumber)
      Search the source position corresponding to the beginning of a given line number Line numbers are 1-based, and relative to the scanner initialPosition. Character positions are 0-based. e.g. getLineStart(1) --> 0 indicates that the first line starts at character 0. In case the given line number is inconsistent, answers -1.
      Specified by:
      getLineStart in interface IScanner
      Parameters:
      lineNumber - int
      Returns:
      int
