||
|   template< class T > static void destroy( Alloc& a, T* p );  | 
(since C++11) | |
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().
Parameters
| a | - | allocator to use for destruction | 
| p | - | pointer to the object being destroyed | 
Return value
(none)
Notes
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.
