Re: [Boost-users] [Serialization] a newbie question about retrieving objects serialized through base class pointers

If BOOST_CLASS_EXPORT is used, the class name is included as an attribute in 
the xml file.

Otherwise, the class_id variable - another xml attribute is used.  This is 
set/recovered by the
"registration" process.

Each way of doing this bookkeeping has its disadvantages and advantages. 
Read the documentation
for further details.

Hi all,
I'm trying to reuse XML archives for some purpose. I'm serializing an array 
of pointers to a base class (let's call it A) containing pointers to derived 
classes (let's call them B and C).
I'm wondering how does Boost distinguish between class types (A, B and 
C)when deserializing from the XML archive? (Is there any information in the 
XML archive or elsewhere giving the class name of the serialized object?)

Regards
