Hello there,

I don't quite know how to use Ada.Streams to read Objects using
dispatching.
To be specific, I have a private tagged type, say Data, and want to
read/write Objects derived from that type. Writing works fine like this:
Data_Pointer: PData; -- an access all Data'class
Str: Stream_Access;
...
Data'Class'Write(Str, Data.all);
But I can't find a solution to read the objects equally nice. From the
Ada95 Rationale I gather I should use 'Input and 'Output somehow, but I'm
just missing an example. Could anyone help me?

Joerg
