[omniORB] Streaming Any's

[Renzo Tomaselli]

Kevin,
        I had exactly the same problem sometime ago, so I wrote a small
package to recurse over Any contents through DynAnys.
The final result is made up of two streams, one for type info, another on=
e
for values.
Stream source/destination is done through callback objects. This package =
is
ORB independent, it has been tested only up to some degree of complexity
contents (on OmniORB 2.8) and it compiles fine on several platforms.
Endianness is taken into account, off course.
I believe performance might be an issue for really complex typecodes and =
it
should depend on the underlying DynAny implem. efficiency; however I have=
 no
figures so far (nor documentation).
I'll be glad to send you its C++ sources if you are interested in.
