1 1)Copy Parser.jjt in a dedicated directory.

     3 2) Grammar modificatiobns:

     4 Grammar located in file Parser.jjt :

     5 

     6 3) Command :

     7 /usr/lang/JAVA/JavaCC_2.0/bin/jjtree Parser.jjt

     8 /usr/lang/JAVA/JavaCC_2.0/bin/javacc Parser.jj

     9 

    10 4) Files to copy back in IPAcl directory:

    11 If you added new node (eg :IpV6Address()) copy the JDM file (eg:JDMIpV6Address.java)

    12 In any cases copy back (These files must be checkedout in IPAcl directory):

    13 ASCII_CharStream.java

    14 JJTParserState.java

    15 ParseException.java

    16 Parser.java

    17 ParserConstants.java

    18 ParserTokenManager.java

    19 ParserTreeConstants.java

    20 TokenMgrError.java

    21 

    22 5) You need to modify any JDM files you copied back. Lauch the compilation and you will see what is wrong.

    23 Have a look to similar nodes in order to see how to modify. Some protected methods have to be overloaded.

    24 

    25 6) Once your updates are running, copy back:

    26 Parser.jj

    27 Parser.jjt

    28 

    29 7) DONE.
