boost :: property_tree :: ptree序列化和反序列化 [英] boost::property_tree::ptree serializing and deserializing

问题描述

我正在读取xml文件并将其存储在boost :: property_tree :: ptree pt(object)中.

I am reading the xml file and storing into boost::property_tree::ptree pt(object).

我正在尝试使用ptree_serialization.hpp

I am trying to serialize this ptree object using the method serialize() defined in ptree_serialization.hpp

boost::property_tree::serialize(ar,pt,1);

当我使用上面的代码时，我收到错误消息；

When i use above code i get the error as;

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> > >&]()))’

如果我做错了事，请告诉我.您能否让我知道我们是否可以序列化xml解析的属性ptree对象.

Could you please let me know if i am doing something wrong. Could you please let me know if we can serialize the xml parsed property ptree object.

推荐答案

您应按预期使用存档界面:

You should use the archive interface as intended: doc

ar << pt;

或

ar >> pt;

版本是使用 BOOST_CLASS_VERSION(Type，version)配置的，但这是在属性树的实现中

The version is as configured using BOOST_CLASS_VERSION(Type, version) but that's in the implementation of Property Tree

还记得

#include <boost/property_tree/ptree_serialization.hpp>
