Hello
everyone,
I'm new to boost in general, as
well as to the serialization library, so I expect that I'm probably
overlooking a few things.
I have searched the archives, and
I've seen threads that are clearly related to what I'm doing, but their
approaches were a bit different than mine (ie. some had the option of
including concrete classes directly).
General
Info:
I'm using boost
1.35.0.
My target platform is Windows
XP.
I'm building with MSVC8
SP1.
What I
Need:
I'm building an interface-driven
library (all the exposed classes are pure abstract
interfaces).
This library resides in its own
DLL, but we can assume that it is always loaded when we're serializing
data.
The concrete classes in this
library (not exposed) implement boost serialization
support.
External applications should be
able to link against boost, create archives, and use them to serialize my
library's objects through my library's interface
pointers.
What I
Tried:
I've attached an MSVC8 solution
with a sample executable and dll.
The library exposes an interface,
hides a concrete implementation of the interface, and exposes a factory
function for retrieving an instance.
The application retrieves an
instance of the class, instantiates a polymorphic binary archiver, and
serializes the object through the interface pointer using the
archiver.
What Goes
Wrong:
In the release configuration, the
test program appears to work.
In the debug configuration, the
app fails an assert (extended_type_info.cpp:74 lookup(eti) ==
m_self->m_map.end()). This seems to be the multiple-registration
issue which has been discussed in earlier
threads.
Why doesn't the assertion fail in
release?
My
Workaround:
I've seen it mentioned in earlier
threads that I should move the actual serialization calls into the DLL.
To that end, I created a
MyLibrarySerializer class which simply forwards the serialization
call.
This seems to work, but since I
just started using this library, I can't tell if I've overlooked a better
solution or if I'm introducing some obscure bugs using this
method.
Questions:
Will my solution work the way I
expect it to (Am I overlooking any major
pitfalls)?
Am I overlooking a better solution
(Is there a way to accomplish this without introducing the MyLibrarySerializer
class)?
Why does my original solution
appear to work in the release configuration?
