    • TslLexer

      public TslLexer(Reader in, String unit)
      Creates a new scanner There is also a java.io.InputStream version of this constructor.
      Parameters:
      in - the java.io.Reader to read input from.

    • TslLexer

      public TslLexer(InputStream in, String unit)
      Creates a new scanner. There is also java.io.Reader version of this constructor.
      Parameters:
      in - the java.io.Inputstream to read input from.

  • Method Details

    • yyclose

      public final void yyclose() throws IOException
      Closes the input stream.
      Throws:
      IOException

    • yyreset

      public final void yyreset(Reader reader)
      Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to ZZ_INITIAL.
      Parameters:
      reader - the new input stream

    • yystate

      public final int yystate()
      Returns the current lexical state.

    • yybegin

      public final void yybegin(int newState)
      Enters a new lexical state
      Parameters:
      newState - the new lexical state

    • yytext

      public final String yytext()
      Returns the text matched by the current regular expression.

    • yycharat

      public final char yycharat(int pos)
      Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster
      Parameters:
      pos - the position of the character to fetch. A value from 0 to yylength()-1.
      Returns:
      the character at position pos

    • yylength

      public final int yylength()
      Returns the length of the matched text region.

    • yypushback

      public void yypushback(int number)
      Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method
      Parameters:
      number - the number of characters to be read again. This number must not be greater than yylength()!

    • next_token

      public Symbol next_token() throws IOException
      Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.
      Specified by:
      next_token in interface Scanner
      Returns:
      the next token
      Throws:
      IOException - if any I/O-Error occurs
