gmx::DefaultInitializationAllocator< T, A > Class Template Reference

#include <gromacs/utility/include/gromacs/utility/defaultinitializationallocator.h>

Inherits A.

Description

template<typename T, typename A = std::allocator<T>>
class gmx::DefaultInitializationAllocator< T, A >

Allocator adaptor that interposes construct() calls to convert value initialization into default initialization.

This can be used to avoid initialization e.g. on resize() in std::vector.

Constructs an object and default initializes.

Todo:

Use std::is_nothrow_default_constructible_v when CUDA 11 is a requirement.
