Java2HTML改造手记(4)

Java2HTML改造手记(4)

 

 

原来这是一个判断当前参数的方法:

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

    "help", "h", "?", "/?"

}))

        {

            System.out.println(O07.O08);

            return false;

        }

这一段是帮助系统,既然我们要修改,那么先把帮助系统处理了.就当咱们肯定能把这个修改成功完成.

目标锁定O07.O08(这是一个final static String):

    public O07()

    {

    }

 

    static

    {

        O0995 = System.getProperty("line.separator");

        if(O0995 == null)

        {

            System.out.println("Warning:System Property line.separator not defined/n");

            O0995 = "/r/n";

        }

        O0997 = "Copyright (c) 2000-2003 Polygon Enterprises." + O0995 + "New Versions available from http://www.java2html.com" + O0995 + "(type j2h with no arguments to get help)";

        O08 = O0995 + "Usage: [j2h|java j2h|java -jar j2h.jar][options]"

        + O0995 + "-d <destination>    Destination output directory"

        + O0995 + "-js <java source>    Java Source directory"

        + O0995 + "-jd <javadoc> [web_reference]  JavaDoc Source directory"

        + O0995 + "-m <margin>      Margin Size (with Line Numbers)"

        + O0995 + "-t <tabsize>      Tab size"

        + O0995 + "-n <name>      Title Name"

        + O0995 + "-nh        Prevents the header from being displayed"

         + O0995 + "-nf        Prevents the footer from being displayed"

        //我在这里添加了encoding的帮助信息

        + O0995 +"-encoding  set the html /"charset/""

        +O0995 + "-s         Simple output, just include the Java source and stylesheet.css files"

        + O0995 + "-h (or no arguments)    This Help" + O0995

        + O0995 + "Edit generated stylesheet.css file to change colours & styles"

        + O0995 + "View generated index.html in browser to see results after running"

        + O0995;

    }

 

现在使用java2html的时候已经有了对encoding的帮助信息了.

 

String as2[] = O010(new String[] {"javasource", "js"}, false, -1);

帮助信息后我们看到了类似这样的方法调用,看来这是判断参数内容的方法了

private String[] O010(String as[], boolean flag, int i)

        throws BadOptionException

    {

        int j = 0;

        int k = 0;

        Vector vector = new Vector();

        for(; j < O02.length; j++)

        {

            for(int l = 0; l < as.length; l++)

            {

                if(!O02[j].equalsIgnoreCase("-" + as[l]))

                {

                    continue;

                }

                O03[j] = true;

                j++;

                if(k == i)

                {

                    throw new BadOptionException(as[0] + " should only be set " + i + " time(s)");

                }

                if(j >= O02.length)

                {

                    throw new BadOptionException("Value not set for " + as[0]);

                }

                O03[j] = true;

                vector.addElement(O02[j]);

                k++;

                break;

            }

 

        }

 

        if(flag && k == 0)

        {

            throw new BadOptionException(as[0] + " needs to be set");

        } else

        {

            return O026(vector);

        }

    }

原来这个方法是把用户送进来的参数(as)和java2html默认的参数比较,如果是java2html的参数那么把用户的参数取值.

我们先把咱们的参数添加上吧.

//添加我们自定义的参数

        String as3[] = O010(new String[] {

            "encoding", "encoding"

        }, false, -1);

//同样依葫芦画瓢

        if(as3.length > 0)

        {

            java2html.setEncoding(as3[0]);

        }

这样用户的参数就送进了as[]了.

不过现在java2html中并没有setEncoding方法.我们的添加一个.

回到java2html.java中添加:

//我在这里设定了默认的字符编码,因为utf-8基本上支持所有的字符编码.

private String encoding="UTF-8";

//添加一个新方法

    public void setEncoding(String strEncoding){

        encoding=strEncoding;

}

这样,用户的参数就已经送到java2html类中了.

 

欲知后事如何,且听下回分解.
