Я создал два специальных типов, которые я хочу использовать в моем get_property_function.hpp в моем приложении:подталкивание :: Определение параметров функции не работает
typedef boost::function<std::string()> GetFunction;
typedef map<std::string, GetFunction> PropertyToGetFunction;
typedef boost::function<std::string (LPARAM)> GetEventFunction;
typedef map<std::string, GetEventFunction> PropertyToGetEventFunction;
Я определяю следующие строки в моем PropertyManager.hpp:
PropertyToGetFunction create_get_map();
PropertyToGetEventFunction create_event_get_map();
PropertyToGetFunction property2getFunction;
PropertyToGetEventFunction property2getEventFunction;
я реализую их в моем PropertyManager.cpp:
PropertyToGetFunction PropertyManager::create_get_map()
{
PropertyToGetFunction property2getFunction;
property2getFunction[string("1.1.3.4.1.1")]=&getReceiptPrinter_DeviceCapability;
...
return property2getFunction;
}
PropertyToGetEventFunction PropertyManager::create_event_get_map()
{
PropertyToGetEventFunction property2getEventFunction;
property2getEventFunction[string("105")]=&getPTRRetractBinThreshold_UserEvent;
...
return property2getEventFunction;
}
методы I присвоенные к моей карте определены в get_property_function.
get_property_function.hpp:
...
std::string getPTRRetractBinThreshold_UserEvent(LPARAM lParam);
...
get_property_function.cpp:
...
std::string getPTRRetractBinThreshold_UserEvent(LPARAM lParam)
{
string result = "";
//I will do some process in here and will save it in result var.
return result;
}
...
Я использую getPropertyValue найти правильный метод в моей карте:
string PropertyManager::getPropertyValue(string property_id)
{
string result_value = "No Property Found";
if (!isReadable(property_id))
{
return "Error";
}
else
{
PropertyToGetFunction::const_iterator it =property2getFunction.find(property_id);
if (it != property2getFunction.end())
{
GetFunction function = it->second;
result_value = function();
}
}
return result_value;
}
string PropertyManager::getPropertyValue(string property_id, LPARAM lParam)
{
string result_value = "No Property Found";
if (!isReadable(property_id))
{
return "Error";
}
else
{
PropertyToGetEventFunction::const_iterator it = property2getEventFunction.find(property_id);
if (it != property2getEventFunction.end())
{
GetEventFunction function = it->second;
result_value = function(lParam);
}
}
return result_value;
}
getPropertyValue(string property_id) работает нормально и У меня нет проблем с этим, но getPropertyValue(string property_id, LPARAM lParam) вызывает ошибку компиляции:

я уверен, что есть что-то не так с моим определением параметра в boost::function. Можете ли вы сказать мне, что я делаю неправильно?
Что такое "property_manager.cpp (189)"? Каков код на этой строке? –
property2getFunction [string ("105")] \t \t \t \t = & getPTRRetractBinThreshold_UserEvent; –
И что такое подпись 'getPTRRetractBinThreshold_UserEvent'? –
