源代码 /** * @brief Removes last element. * * This is a typical stack operation. It shrinks the %list by * one. Due to the nature of a %list this operation can be done * in constant time, and only invalidates iterators/references to * the element being removed. * * Note that no data is returned, and if the last element's data * is needed, it should be retrieved before pop_back() is called. */ void pop_back() { this->_M_erase(this->_M_impl._M_node._M_prev); } |
