I have a list of MyClass: struct MyClass { bool is_old_result(int lifetime); }; std::list<MyClass> results;
Is there any performance advantage to be had when using template parameters with static member functions instead of functor-style predicates??
I\'m currently having a problem with a class template in C++. I\'m currently making a hash table. I\'m using a functor as a class template to specify my hash function for each instance of a table.
I have a class Foo which is used in a small standalone project. It has a class definition in Foo.h with the implementation for the class\' member functions in an implementation file Foo.cpp.
I was experimenting with the STL algorithms and more specific with the for_each function. I tried a simple use case for concatenating a vector of strings. Note that this is probably not a good and/or
Something like this : std::bind1st(std::mem_fun(&istream::get ??), cin). This does not s开发者_StackOverflow中文版eem to work for me.
The key reason this works is that for_each () doesn’t actually assume its third argument to be a function.
hey, i implemented the following functor: struct CompareCatId : public std::binary_function<Vehicle*, Vehicle*, bool>
What is the problem with this code ? this code is giving me lots of syntax errors. Also I would like to know why functors are used in C++.
I\'ve the following situation: module type M = sig type s = ...end module Make(P: Something) : (M with type s = P.t) = struct
