public member function

<vector>

void swap (vector& x);

static void swap (reference ref1, reference ref2);

void swap (vector& x);

static void swap (reference ref1, reference ref2) noexcept;

Swap containers or elements

A static signature to swap individual elements (bits) is added on vector<bool>.

x

Another vector<bool> container. Sizes may differ.

ref1, ref2

References to elements.
reference is a member type that accesses individual elements while providing an interface that simulates a reference to bool (see reference for more info).
