c++ - How to iterate through such a map? How to fix 8 scary C2784 errors? -

so seek compile such code:

bool server_utils::find_service_by_name_iterator_function(std::pair<boost::shared_ptr<service>, server_utils::service_description> const & element, std::string name) const { homecoming element.second.name == name; } server_utils::service_description server_utils::stop_service_by_name(std::string name) { typedef std::map<boost::shared_ptr<service>, server_utils::service_description> map_t; map_t::iterator map_it = std::find_if(description.service_map.begin(), description.service_map.end(), std::bind1st(std::ptr_fun(&server_utils::find_service_by_name_iterator_function), name)); if (map_it != description.service_map.end()) { description.service_map.erase (map_it); } else { throw std::runtime_error("service such name not found map not found!"); } }

where

struct service_description { //a service must have std::string name; std::string library_name; std::string class_name; std::string root_file_system_directory; boost::property_tree::ptree service_custome_properties_tree; //a service might have std::vector<std::string> set_of_url_rules; boost::unordered_multimap<std::string, std::string> set_of_header_rules; boost::unordered_multimap<std::string, std::string> set_of_arguments_rules; std::set<std::string> url_extensions; std::string root_service_web_path; };

but unusual errors:

error c2784: 'std::pointer_to_binary_function<_arg1,_arg2,_result,_result(__cdecl *)(_arg1,_arg2)> std::ptr_fun(_result (__cdecl *)(_arg1,_arg2))' : not deduce template argument '_result (__cdecl *)(_arg1,_arg2)' 'bool (__thiscall server_utils::* )(const std::pair<_ty1,_ty2> &,std::string) const' error c2784: 'std::pointer_to_binary_function<_arg1,_arg2,_result,_result(__fastcall *)(_arg1,_arg2)> std::ptr_fun(_result (__fastcall *)(_arg1,_arg2))' : not deduce template argument '_result (__fastcall *)(_arg1,_arg2)' 'bool (__thiscall server_utils::* )(const std::pair<_ty1,_ty2> &,std::string) const' error c2784: 'std::pointer_to_unary_function<_arg,_result,_result(__cdecl *)(_arg)> std::ptr_fun(_result (__cdecl *)(_arg))' : not deduce template argument '_result (__cdecl *)(_arg)' 'bool (__thiscall server_utils::* )(const std::pair<_ty1,_ty2> &,std::string) const' error c2784: 'std::pointer_to_unary_function<_arg,_result,_result(__stdcall *)(_arg)> std::ptr_fun(_result (__stdcall *)(_arg))' : not deduce template argument '_result (__stdcall *)(_arg)' 'bool (__thiscall server_utils::* )(const std::pair<_ty1,_ty2> &,std::string) const' , on...

what shall do? how prepare code? can boost.function or boost.bind help me?

use boost::bind; it's far smarter:

map_t::iterator map_it = std::find_if( description.service_map.begin(), description.service_map.end(), boost::bind(&server_utils::find_service_by_name_iterator_function, this, name));

intellij idea - Update external libraries with intelij and java - simple plenty really. i'm using apache jars, i'll create changes jar's every often. these jars listed external libs in intelij (i.e classpath looking install dir of jar's). when create changes intelij doesn't seem know new implementation. have remove jar external library , re-ad it. does know have intelij picks changes automatically ? i've done clean , rebuild project had little effect. you can go preferences -> build, execution, deployment -> build tools -> maven -> importing , check box says import maven projects automatically . in mac, can command + shift + a , come in action reimport , click on reimport maven projects . intellij-idea
