Yes sorry, I should have given some more background info in the first place.

This occurs when compiling JD 2.2.0 :

It's impossible to define new types of streams in giomm. Firstly, it's
impossible to inherit from InputStream and FilterInputStream, and secondly even
if I inherit from a constructible type, the stream is not polymorphic (i.e. it
simply doesn't work in the situations that matter).

This could be solved by giving Gio::InputStream an Gio::OutputStream a couple
of vfuncs that correspond to the virtual methods of GInputStream and
GOutputStream GObjects, in a matter similar to e.g. Gtk::CellRenderer.

------- Comment #1 from Murray Cumming  2009-02-20 19:24 UTC -------
Yes, we chose not to wrap the vfuncs (via _WRAP_VFUNC()) in giomm, because we
thought that almost nobody would want to do this and we were worried about the
bugs it could introduce in the short term.

But if you have a real-world test case, and a real use for them, we could add
these in a future ABI break. That's likely to happen in the nearish future, if
the glib/gtk+ 3.0 ABI break really happens. So a patch would be welcome.

------- Comment #2 from Krzysztof Kosi?ski  2009-02-20 20:45 UTC -------
A real-world use case would be a base64-encoded stream, or streams that write
compressed files. This way if I have a function in an image processing app like
this:

void Document::save_png_image(Glib::RefPtr<Gio::OutputStream>)

and I want to create an SVG document which embeds this PNG as a base64-encoded
data: URI, I can pass it a Base64OutputStream, which is derived from
Gio::FilterOutputStream and writes the base64-encoded data directly into the
output file. I could do this in a roundabout way by base64-encoding data
written to a MemoryOutputStream, but then I would need to save the entire file
into memory, increasing the memory footprint of my application.
