std::vector<T,Allocator>::clear

void clear();

void clear() noexcept;

Erases all elements from the container. After this call, size() returns zero.

Invalidates any references, pointers, or iterators referring to contained elements. Any past-the-end iterators are also invalidated.

Leaves the capacity() of the vector unchanged (note: the standard's restriction on the changes to capacity is in the specification of vector::reserve, see [1]).

Parameters

(none).

Return value

(none).

Complexity

Linear in the size of the container, i.e., the number of elements.
