源代码 /** * @brief Remove all elements satisfying a predicate. * @param Predicate Unary predicate function or object. * * Removes every element in the list for which the predicate * returns true. Remaining elements stay in list order. Note * that this function only erases the elements, and that if the * elements themselves are pointers, the pointed-to memory is * not touched in any way. Managing the pointer is the user's * responsibilty. */ template<typename _Predicate> void remove_if(_Predicate); |
