Ja Java2HTML改造手记(3)
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.
// Source File Name: O01.java
package com.java2html;
import java.io.File;
import java.io.PrintStream;
import java.util.Vector;
// Referenced classes of package com.java2html:
// BadOptionException, Java2HTML, JavaDoc, O07

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.
