Is there a good reason to have FileResourceStream final? I may be
missing a better way to use it, but I feel I'm jumping through some
serious hoops because I want to override one method of this class. What
I'd like to do is this:
add(new ResourceLink("downloadLink", new Resource() {
public IResourceStream getResourceStream() {
return new FileResourceStream(
new wicket.util.file.File(filename)) {
public String getContentType() {
if (filename.toLowerCase().endsWith(".doc")) {
return "application/msword";
}
return super.getContentType();
}
};
}
}));
But because FileResourceStream is final, I need to do something like
this instead:
add(new ResourceLink("downloadLink", new Resource() {
public IResourceStream getResourceStream() {
return new IResourceStream() {
FileResourceStream frs = new FileResourceStream(
new wicket.util.file.File(filename));
public String getContentType() {
if (filename.toLowerCase().endsWith(".doc")) {
return "application/msword";
}
return frs.getContentType();
}
public void close() throws IOException {
frs.close();
}
public InputStream getInputStream()
throws ResourceStreamNotFoundException {
return frs.getInputStream();
}
public Locale getLocale() {
return frs.getLocale();
}
public long length() {
return frs.length();
}
public void setLocale(Locale locale) {
frs.setLocale(locale);
}
public Time lastModifiedTime() {
return frs.lastModifiedTime();
}
};
}
}));
Of course I should probably move this to a separate class, but,
regardless, if it weren't final, this would be easier.
Of course any suggestions for how to do this more easily would also be
welcome! :-)
Thanks,

P.S. This class has the following Javadoc comment for its one (public)
constructor: "Private constructor to force use of static factory
methods." I don't think there is any static factory for this. There
certainly isn't one in the class itself.
