Re: [Boost-users] How to override the init() in the xmlserializationlibrary..

Thanks,

 

I could get past the header with the "no_header" flag. Also I tried the
demo and it puts the </boost_serialization> tag correctly but I do not
get that tag in my case.

 

Does the friend declaration for the stream << operators required in the
classes that implement serialization. I do not have this declaration but
it seems to work fine.

 

The other thing is that I get the xml from outside source and when
reading in it might have a header which will be different from the one
boost has.

 

That was the reason I wanted to overwrite the init function to have
custom header. Now I generate o/p with no header but then still have to
read in the header. The only other way is I eat the header. Is there
some cleaner?

 

But at least I know a way around. Thanks fro your time and help.

 

Thanks,

Sangeeta

A couple of things:

 

a) you might try opening the the archive with the "no_header" flag.

b) I checked the output of my tests and I see that they do contain the
end tag

</boost_serialization>.  You might try running one of tests and/or demos

to verify that these work on your system.  If they do, investigate what
your

program is doing differently

c) I looked in the code in "basic_xml_oarchive.ipp" and it does contain
code

to append </boost_serialization> at the end of the output.  You should

investigate why this code isn't being called.  If this is due to an
error

in the library- we would be interested in the details.

        Hi,

         

        I have a need to be able to specify my own init routine for the
xml serialization. I tried deriving a new archive from xml_oarchive_impl
and tried to have a init() function there but that does not get invoked.

         

        I am using boost serialization library ver 1.32.

         

        The xml that is generated by the library is malformed. It
generates the following line without corresponding end tag

         

        <boost_serialization signature="serialization::archive"
version="3">

         

         

        There is no </boost_serialization> in the o/p xml.

         

        Also my requiremet is that I do not generate this tag.

         

        Thanks,

        Sangeeta
