路径。
this.prefixLength = fs.prefixLength(this.path);
Properties pro=new Properties();
try {
pro.load(new FileInputStream(this)); //读取filemap.properties.
Enumeration enumeration=pro.propertyNames();
while(enumeration.hasMoreElements()){
String sourcepath=(String)enumeration.nextElement();
String targetpath=pro.getProperty(sourcepath);
filemaps.put(sourcepath, targetpath); //保存到filemaps静态对象里。
}
} catch(FileNotFoundException e1){
return;
} catch(IOException e2){
return;
}
}
我们还需要一个私有方法转换路径。
/**
* Get Virutal Path string
* @param name 原UNIX/Linux路径。
* @return 新windows路径。
*/
private String getVirtualPath(String name){
Iterator sources=filemaps.keySet().iterator();
while(sources.hasNext()){
String source=(String)sources.next();
if(name.startsWith(source)==true){
//当原路径包含filemaps里某一个source路径时,将原路径转换为新的target路径。
String target=(String)filemaps.get(source);
name=target+name.substring(source.length());
}
}
return name;
}
好了,现在准备在java.io.File里调用这两个方法。
/**
* Creates a new File instance by converting the given
* pathname string into an abstract pathname. If the given string is
* the empty string, then the result is the empty abstract pathname.
*
* @param pathname A pathname string
* @throws NullPointerException
* If the pathname argument is null
*/

//new function
initmaps();

throw new NullPointerException();
}

this.path = fs.normalize(pathname);
