t1.*fn when fn is a pointer to member data of a class T and t1 is an object of type T or a reference to an object of type T or a reference to an object of a type derived from T (*t1).*fn when fn is a pointer to member data of a class T and t1 is not one of the t...
boost::bind is a generalization of the standard functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments into arbitrary positions.译:...
Pointers to member functions and pointers to data members are not function objects, because they do not supportoperator(). For convenience,bindaccepts member pointers as its first argument, and the behavior is as ifboost::mem_fn(把成员函数转换成函数对象)has been used to convert the member poin...
bind makes a copy of the provided function object. boost::ref and boost::cref can be used to make it store a reference to the function object, rather than a copy. This can be useful when the function object is noncopyable, expensive to copy, or contains state; ...
从boost::bind开始学习Boost库:boost::bind is a generalization of the standard functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments...
I'm using Boost 1.73 the error is reported in: c:\boost\boost_1_73_0\boost\bind\mem_fn_template.hpp(271): error C2672: 'get_pointer': no matching overloaded function found c:\boost\boost_1_73_0\boost\bind\mem_fn_template.hpp(286): note: see reference to function template ...
function和bind其实在c++11之前,在boost库中就有相应的实现,在c++11才被纳入了标准库的体系,而lamdba是c++11新引入的语法糖。再看这篇文章之前一定会纳闷为什么要把这三个东西放到一起来写,这三个东西的联系是…

Everything is fully automatic. Raising a C++ exception will reject thePromise. Enabling async mode will allow the JS user to potentially call the C++ method while a previous invocation is still running. If the C++ method is not fully reentrant, a wrapper with a lock mechanism should be implem...
考虑下面这个简单的类,status, 我们将用它来示范 Boost.Bind 的易用性和强大的功能。 class status { std::string name_; bool ok_; public: status(const std::string& name):name_(name),ok_(true) {} void break_it() { ok_=false; } bool is_broken() const { return ok_; } void report...
