std::experimental::erase (std::forward_list)

Defined in header <experimental/forward_list>
template <class T, class A, class U>
void erase(std::forward_list<T, A>& c, const U& value);
 (library fundamentals TS v2)

Erases all elements that compare equal to value from the container. Equivalent to c.remove_if([&](auto& elem) { return elem == value; });

Parameters

c - container from which to erase
value - value to be removed

Complexity

Linear.

Example

#include <experimental/forward_list>
#include <iostream>
 
auto show = [](const auto& container) {
    for (auto e : container) {
        std::cout << e;
    }
    std::cout << '\n';
};
 
int main()
{
    std::forward_list<int> data{1,1,1,4,1,1,1,2,1,1,1};
    show(data);
    std::experimental::erase(data, 1);
    show(data);
}

Output:

11141112111
42


Notes

Unlike std::forward_list::remove, this function template accepts heterogenous types and does not force a conversion to the container's value type before invoking the == operator.
