推導指南(C++17)

 

定義於標頭檔案 <scoped_allocator>
template< class T > void destroy( T* p );		(C++11 起)

使用外部分配器呼叫 p 所指向物件的解構函式，透過呼叫

std::allocator_traits<OUTERMOST>::destroy(OUTERMOST(*this), p)

其中 OUTERMOST 是透過呼叫 this->outer_allocator() 返回的型別，然後在此呼叫的結果上遞迴呼叫 outer_allocator() 成員函式，直到達到沒有此類成員函式的型別。

引數

p

-

指向將被銷燬的物件的指標

返回值

(無)
