      • text

        public java.lang.String text()
        Specified by:
        text in interface Lexer

        throws java.io.IOException
        Specified by:
        lex in interface Lexer
        Throws:
        java.io.IOException

        public int getLine()
        Specified by:
        getLine in interface Lexer

      • getColumn

        public int getColumn()

      • getCodeBody

        public java.lang.String getCodeBody()
        Specified by:
        getCodeBody in interface Lexer

      • yyclose

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

      • yypushStream

        public final void yypushStream​(java.io.Reader reader)
        Stores the current input stream on a stack, and reads from a new stream. Lexical state, line, char, and column counting remain untouched. The current input stream can be restored with yypopstream (usually in an <> action).
        Parameters:
        reader - the new input stream to read from
        See Also:
        yypopStream()

      • yypopStream

        public final void yypopStream()
                       throws java.io.IOException
        Closes the current input stream and continues to read from the one on top of the stream stack.
        Throws:
        java.util.EmptyStackException - if there is no further stream to read from.
        java.io.IOException - if there was an error in closing the stream.
        See Also:
        yypushStream(java.io.Reader)

      • yymoreStreams

        public final boolean yymoreStreams()
        Returns true iff there are still streams left to read from on the stream stack.

      • yyreset

        public final void yyreset​(java.io.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
        See Also:
        yypushStream(java.io.Reader), yypopStream()

      • 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 java.lang.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()!

      • yylex

        public int yylex()
          throws java.io.IOException
        Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.
        Returns:
        the next token
        Throws:
        java.io.IOException - if any I/O-Error occurs
