Deduction guides(C++17)

 

Defined in header <scoped_allocator>
template< class T > void destroy( T* p );		(since C++11)

Uses the outer allocator to call the destructor of the object pointed to by p, by calling

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

where OUTERMOST is the type that would be returned by calling this->outer_allocator(), and then calling the outer_allocator() member function recursively on the result of this call until reaching the type that has no such member function.

Parameters

p

-

pointer to the object that is going to be destroyed

Return value

(none)

destroy [static]	destructs an object stored in the allocated storage (function template)
destroy (until C++20)	destructs an object in allocated storage (public member function of std::allocator<T>)
