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( & ptree::put ), boost::ref( tree ), "Values.value", _1 ) );
Try this:
...
static_cast
Hi Sebstian
Thanks for that, I thought that should work too, but seems there's still an overload problem!
#include <algorithm>
#include <vector>
#include 
#include 
#include 
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.
