basic_streambuf::pbackfail
 
virtual ~basic_streambuf();
この破壊は空になります。このbasic_streambuf(ポインタとロケール)のメンバーは、このデストラクタが返された後に通常のオブジェクトの破壊シーケンスに従って破棄されています。しかし、それはパブリック仮想宣言されているので、それが基底クラスへのポインタを介して削除するstd::basic_streambufから派生しているオブジェクトを可能に.
Original:
This destruction is empty: the members of this basic_streambuf (the pointers and the locale) are destructed in accordance with the usual object destruction sequence after this destructor returns. However, since it is declared public virtual, it allows the objects that are derived from std::basic_streambuf to be deleted through a pointer to base class.
