std::hive<T,Allocator>::clear
From cppreference.com
void clear() noexcept;
|
(since C++26) | |
Erases all elements from the container. After this call, size() returns zero.
Invalidates any references, pointers, and iterators referring to contained elements.
Complexity
Linear in the size of the container, i.e., the number of elements.
Example
Run this code
#include <hive>
#include <print>
int main()
{
std::hive<int> v{1, 2, 3};
std::println("Before clear: {}, size={}, capacity={}", v, v.size(), v.capacity());
v.clear();
std::println("After clear: {}, size={}, capacity={}", v, v.size(), v.capacity());
}
Possible output:
Before clear: [1, 2, 3], size=3, capacity=76
After clear: [], size=0, capacity=76
