std::experimental::erase(std::list)(3) C++ Standard Libary std::experimental::erase(std::list)(3)

NAME

std::experimental::erase(std::list) - std::experimental::erase(std::list)

Synopsis


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


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

// Run this code


#include <experimental/list>
#include <iostream>


auto show = [](const auto& container)
{
for (auto e : container)
std::cout << e;
std::cout << '\n';
};


int main()
{
std::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::list::remove, this function template accepts heterogeneous types and
does not force a conversion to the container's value type before invoking the ==
operator.
