Hi All

Is it possible and practical to use the put and get methods of Boost.PropertyTree with std

algorithms?

I've written this snippet, which doesn't compile, which I think is because I have not correctly

expressed the return type of "put()". Is it possible to do this?

Yes, the put() overloads all return the affected tree node.

    for_each( boost::begin( v ), boost::end( v ),

            bind( static_cast<void (ptree::*)( const std::string &, unsigned )>( & ptree::put ), boost::ref( tree ), "Values.value", _1 ) );

Try this:

static_cast<ptree& (ptree::*)(...)> 

Hi Sebstian

Thanks for that, I thought that should work too, but seems there's still an overload problem!

#include <algorithm>

#include <vector>

#include <boost/range.hpp>

#include <boost/bind.hpp>

#include <boost/property_tree/ptree.hpp>

int main( )

{

    using boost::property_tree::ptree;

    std::vector<unsigned> v;

    ptree tree;

    ptree & ( ptree::*myput )( const std::string &, unsigned ) = & ptree::put;

The first argument should be a ptree::path_type (= string_path<char>), not std::string.
