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 heterogeneous types and does not force a conversion to the container's value type before invoking the == operator.
