      • getTokenStart

        public final int getTokenStart()
        Specified by:
        getTokenStart in interface com.intellij.lexer.FlexLexer

      • getTokenEnd

        public final int getTokenEnd()
        Specified by:
        getTokenEnd in interface com.intellij.lexer.FlexLexer

      • reset

        public void reset​(java.lang.CharSequence buffer,
                  int start,
                  int end,
                  int initialState)
        Specified by:
        reset in interface com.intellij.lexer.FlexLexer

      • yystate

        public final int yystate()
        Returns the current lexical state.
        Specified by:
        yystate in interface com.intellij.lexer.FlexLexer

      • yybegin

        public final void yybegin​(int newState)
        Enters a new lexical state
        Specified by:
        yybegin in interface com.intellij.lexer.FlexLexer
        Parameters:
        newState - the new lexical state

      • yytext

        public final java.lang.CharSequence 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

      • 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()!

        advance in interface com.intellij.lexer.FlexLexer
        Returns:
        the next token
        Throws:
        java.io.IOException - if any I/O-Error occurs
