class uninitialized_buffer Uninitialized type safe memory storage
uninitialized_buffer
provides a typed buffer allocated from a given memory resource. It handles alignment and release of the allocation. The memory is uninitialized, so that a user needs to ensure elements are properly constructed.In addition to being type safe,
uninitialized_buffer
also takes a set of properties to ensure that e.g. execution space constraints are checked at compile time. However, we can only forward stateless properties. If a user wants to use a stateful one, then they need to implement get_property(const device_buffer&, Property).- Template Parameters
_Tp – the type to be stored in the buffer
_Properties... – The properties the allocated memory satisfies

Public Functions
-
inline uninitialized_buffer(__resource __mr, const size_t __count)
Constructs a
uninitialized_buffer
, allocating sufficient storage for__count
elements through__mr
.Note
Depending on the alignment requirements of
T
the size of the underlying allocation might be larger thancount * sizeof(T)
.Note
Only allocates memory when
__count
> 0- Parameters
__mr – The memory resource to allocate the buffer with.
__count – The desired size of the buffer.
-
uninitialized_buffer(const uninitialized_buffer&) = delete
-
uninitialized_buffer &operator=(const uninitialized_buffer&) = delete
-
inline uninitialized_buffer(uninitialized_buffer &&__other) noexcept
Move construction.
- Parameters
__other – Another
uninitialized_buffer
-
inline uninitialized_buffer &operator=(uninitialized_buffer &&__other) noexcept
Move assignment.
- Parameters
__other – Another
uninitialized_buffer
-
inline ~uninitialized_buffer()
Destroys an
uninitialized_buffer
deallocating the buffer.Warning
The destructor does not destroy any objects that may or may not reside within the buffer. It is the user’s responsibility to ensure that all objects within the buffer have been properly destroyed.
-
inline const __resource &get_resource() const noexcept
Returns a c const reference to the any_resource that holds the memory resource used to allocate the buffer
-
inline constexpr void swap(uninitialized_buffer &__other) noexcept
Swaps the contents with those of another
uninitialized_buffer
.- Parameters
__other – The other
uninitialized_buffer
.
