Defined in header <memory>
template< class T >
static void destroy( Alloc& a, T* p );
(C + + 11以来)

Calls the destructor of the object pointed to by p. If possible, does so by calling a.destroy(p). If not possible (e.g. a does not have the member function destroy(), then calls the destructor of *p directly, as p->~T().

[編集] ノート

Because this function provides the automatic fall back to direct call to the destructor, the member function destroy() is an optional Allocator requirement since C++11.
