      • ClojureLexer

        public ClojureLexer()
        Create an empty lexer, yyrset will be called later to reset and assign the reader

      • ClojureLexer

        public ClojureLexer​(java.io.Reader in)

        in - the java.io.Reader to read input from.

    • Method Detail

      • yychar

        public int yychar()
        Description copied from class: DefaultJFlexLexer
        Return the char number from beginning of input stream. This is NOT implemented by JFLex, so the code must be added to create this and return the private yychar field
        Specified by:
        yychar in class DefaultJFlexLexer
        Returns:

      • yyclose

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

      • 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. Internal scan buffer is resized down to its initial length, if it has grown.
        Specified by:
        yyreset in class DefaultJFlexLexer
        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 java.lang.String yytext()
        Returns the text matched by the current regular expression.
        Specified by:
        yytext in class DefaultJFlexLexer
        Returns:

      • 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
        Specified by:
        yycharat in class DefaultJFlexLexer
        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.
        Specified by:
        yylength in class DefaultJFlexLexer
        Returns:

      • 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 Token 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.
        Specified by:
        yylex in class DefaultJFlexLexer
        Returns:
        the next token
        Throws:
        java.io.IOException - if any I/O-Error occurs
