Ja Java2HTML改造手记(3)

XML:namespace prefix = o ns = "urn:schemas-microsoft-com:Office:office" />

先重点看这个:

public static void main(String args[])

{

  ……………….

  java2html = new Java2HTML();

  o01 = new O01(args);

  ……………….

}

参数又跳转到o01上了.那么我们继续,没办法,逆向工程是需要耐心的.

  {

  if(!O03[i])

  {

   throw new BadOptionException("Unkown Argument :" + O02[i]);

  }

  }

  }

}

找到这里:

O01(String as[])

{

O02 = as;

  O03 = new boolean[as.length];

}

看来这里没有作什么,那么我们回到java2html.java文件继续往下看:

public static void main(String args[])

{

…………………..

java2html = new Java2HTML();

  o01 = new O01(args);

  //这里就是了

  if(!o01.O04(java2html))

  {

    return;

  }

  ………………….

}

原来调用了o01.O04方法.看看:

boolean O04(Java2HTML java2html)

  throws BadOptionException

  {

  if(O02.length == 0 || O06(new String[] {

  "help", "h", "?", "/?"

}))

  {

  System.out.println(O07.O08);

  return false;

  }

  String as[] = O010(new String[] {

  "name", "n"

  }, false, 1);

  if(as.length == 1)

  {

  java2html.setTitle(as[0]);

  }

  java2html.setFooter(O06(new String[] {

  "nofooter", "nf"

  }));

  java2html.setFooter(O06(new String[] {

  "noheader", "nh"

  }));

  java2html.setSimple(O06(new String[] {

  "simple", "s"

  }));

  int ai[] = O012(new String[] {

  "margin", "m"

  }, false, 1);

  if(ai.length == 1)

  {

  java2html.setMarginSize(ai[0]);

  }

  int ai1[] = O012(new String[] {

  "tabs", "t"

  }, false, 1);

  if(ai1.length == 1)

  {

  java2html.setTabSize(ai1[0]);

  }

  String as1[] = O010(new String[] {

  "destination", "d"

  }, false, 1);

  if(as1.length == 1)

  {

  java2html.setDestination(as1[0]);

  }

   String as2[] = O010(new String[] {

  "javasource", "js"

  }, false, -1);

  if(as2.length > 0)

  {

  java2html.setJavaDirectorySource(as2);

  }

  JavaDoc ajavadoc[] = O017(new String[] {

  "javadoc", "jd"

  });

  if(ajavadoc.length > 0)

  {

  java2html.setJavaDoc(ajavadoc);

  }

  O018();

  return true;

  }

欲知后事如何,且听下回分解.
