Does the function object randomElementByWeight constructor get called for every iteration through the loop or can the compiler optimize this away somehow? I want to make sure the rand function is call
I\'m designing a mechanism that will execute a set of unary function objects in sequence. These function objects are assigned during runtime, and the problem is: the parameter type of these function o
The following code computes the average of a particular property of T in the items collection: public double Average<T>(IList<T> items, Func<T, double> selector)
How can I detect the return type and parameter types of nullary and unary function pointers, std::function objects, and functors (including lambdas)?
I\'d like to use std::tm () as the key for an std::map-container. But when I try to compile it, I get a lot(10) of errors.
I recently have got excited by functors and been using them all over the place.Then the situation arose where I needed my functor to perform two different operations and I thought about adding another
I have a set of shared_ptr, and I\'d like to use remove_copy_if with a custom function object for the predicate.I didn\'t know the \"best\" way to do it.Right now, I\'ve got this working:
I\'m new to std::generate and have attempted to structure a program which uses it to initialize vectors. However it\'s behaving differently to my expectations.
I found this code on Wikipedia class compare_class { public: bool operator()(int A, int B) const { return A < B;
The key reason this works is that for_each () doesn’t actually assume its third argument to be a function.
