在典型的实现中,std::ostream_iterator是指向关联std::basic_ostream和指向分隔符字符串中的第一个字符的指针。 写字的时候,std::ostreambuf_iterator更有效,因为它避免了每个字符构造和销毁哨兵对象一次的开销。 成员类型 Member type Definition char_type ...

std::ostream_iterator 是单趟遗留输出迭代器 (LegacyOutputIterator) ,用 operator<< 写入相继 T 类型对象到为之创建迭代器的 std::basic_ostream 对象。每次写操作后写入可选的分隔字符串。写操作在赋值给迭代器时(无论是否解引用)进行。自增 std::ostream_iterator 是无操作。 典型实现中, std::ostream_...
