我正在读取xml文件并存储到boost :: property_tree :: ptree pt(object)。
我正在尝试使用ptree_serialization.hpp中定义的方法serialize()
序列化此ptree对象
boost::property_tree::serialize(ar,pt,1);
当我使用上面的代码时,我得到错误;
boost/serialization/collections_save_imp.hpp:64:9: error: no match for ‘operator<<’ in ‘ar << boost::serialization::make_nvp(const char*, T&) [with T = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >]((* &((boost::iterator_facade<boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, boost::bidirectional_traversal_tag, const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, int>*)(& boost::operator++ [with I = boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, V = std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, TC = boost::bidirectional_traversal_tag, R = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, D = int, typename boost::detail::postfix_increment_result<I, V, R, TC>::type = boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator]((*(boost::iterator_facade<boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, boost::bidirectional_traversal_tag, const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, int>*)(& it)), 0)))->boost::iterator_facade<I, V, TC, R, D>::operator* [with Derived = boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, Value = std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, CategoryOrTraversal = boost::bidirectional_traversal_tag, Reference = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, Difference = int, boost::iterator_facade<I, V, TC, R, D>::reference = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&]()))’
如果我做错了,你可以告诉我吗?如果我们可以序列化xml解析的属性ptree对象,请告诉我。
答案 0 :(得分:1)
您应该按预期使用存档界面:doc
ar << pt;
或
ar >> pt;
版本使用BOOST_CLASS_VERSION(Type, version)
配置,但在属性树的实现中
还要记得
#include <boost/property_tree/ptree_serialization.hpp>
