Class ov::Allocator¶
-
class Allocator¶
Wraps allocator implementation to provide safe way to store allocater loaded from shared library And constructs default based on
newdeletec++ calls allocator if created without parameters Accepts any std::pmr::memory_resource like allocator.Public Functions
-
~Allocator()¶
Destructor preserves unloading order of implementation object and reference to library.
-
Allocator()¶
Default constructor.
-
Allocator(const Allocator &other) = default¶
Default copy constructor.
- Parameters
other – other Allocator object
-
Allocator &operator=(const Allocator &other) = default¶
Default copy assignment operator.
- Parameters
other – other Allocator object
- Returns
reference to the current object
-
Allocator(Allocator &&other) = default¶
Default move constructor.
- Parameters
other – other Allocator object
-
Allocator &operator=(Allocator &&other) = default¶
Default move assignment operator.
- Parameters
other – other Allocator object
- Returns
reference to the current object
-
OPENVINO_SUPPRESS_DEPRECATED_START Allocator(const AllocatorImpl::Ptr &impl)¶
Constructs Allocator from the initialized std::shared_ptr.
- Parameters
impl – Initialized shared pointer
Initialize allocator using any allocator like object.
- Template Parameters
A – Type of allocator
- Parameters
a – allocator object
- OPENVINO_SUPPRESS_DEPRECATED_END void * allocate (const size_t bytes, const size_t alignment=alignof(max_align_t))
Allocates memory.
- Parameters
bytes – The size in bytes at least to allocate
alignment – The alignment of storage
- Throws
Exception – if specified size and alignment is not supported
- Returns
Handle to the allocated resource
-
void deallocate(void *ptr, const size_t bytes = 0, const size_t alignment = alignof(max_align_t))¶
Releases the handle and all associated memory resources which invalidates the handle.
- Parameters
ptr – The handle to free
bytes – The size in bytes that was passed into allocate() method
alignment – The alignment of storage that was passed into allocate() method
-
bool operator==(const Allocator &other) const¶
Compares with other Allocator.
- Parameters
other – Other instance of allocator
- Returns
trueif and only if memory allocated from one Allocator can be deallocated from the other and vice versa
-
