Sorry, I can't explain this.
a) I can't explain how output code would through an exception "unrecognized
XML syntax"
which should only be invoked when an archive is read.
b) the " Robert, Here is the relevant code: ===========================================
from the header file for the class being serialized... #include "boost/serialization/shared_ptr.hpp"
#include "boost/serialization/nvp.hpp"
#include "boost/date_time/posix_time/ptime.hpp"
#include "boost/date_time/posix_time/time_serialize.hpp" . . . private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive& ar, const unsigned int version) {
ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(WkFlo::RetractionMixin);
ar & BOOST_SERIALIZATION_NVP(mNode); ar &
BOOST_SERIALIZATION_NVP(mExportId); ar &
BOOST_SERIALIZATION_NVP(mExportStart); }//serialize() where mNode is a shared_ptr<>, mExportedId is a string, and
mExportStart
is a ptime.
=========================================== from the test source file... #include "boost/archive/xml_iarchive.hpp"
#include "boost/archive/xml_oarchive.hpp"
#include "boost/serialization/shared_ptr.hpp"
#include "boost/serialization/nvp.hpp" . . . void ExportedNode_Test::serializationTest() {
const char* archiveFile = "temp/Exported_Node_archive.xml";
remove(archiveFile); // remove any file with that name
MockNode_ptr BasicNodeObj1(new MockNode(2312)); ExportedNode_ptr testObj_out(new ExportedNode(BasicNodeObj1, "abcd"));
{
// save data to archive
ofstream outStream(archiveFile);
boost::archive::xml_oarchive outArchive(outStream); // write class instance to archive
try {
outArchive << BOOST_SERIALIZATION_NVP(testObj_out);
} catch (exception& ex) { cerr << "write: " <<
ex.what() << endl;} } // archive and stream closed when destructors
are called . . .
} where the outArchive << is what wrote: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!DOCTYPE boost_serialization>
and threw the exception: "unrecognized XML syntax" Is this enough to go on? Merrill
