Allocate()

void Allocate

(

)

Allocate the amount of memory indicated by m_BufferSize, and point each m_Data to each correspondent Tensor so that they are m_Offset bytes separated.

    for (auto& m_AllocatorBufferStoragePair : m_AllocatorBufferStoragePairVector)
    {
        auto& allocator = m_AllocatorBufferStoragePair.first;
        for (auto&& bufferStorage : m_AllocatorBufferStoragePair.second)

StoreMemToAllocate()

void StoreMemToAllocate	(	std::vector< BufferStorage >	bufferStorageVector,
		std::shared_ptr< ICustomAllocator >	customAllocator,
		size_t	typeAlignment = 0
	)

Initialization method to store in m_AllocatorBufferStoragePairVector all information needed.

Parameters

[in]	bufferStorageVector	- Vector of BufferStorage.
[in]	customAllocator	- Pointer to ICustomAllocator.
[in]	typeAlignment	- Optional parameter. Value of which the size of each value has to be multiple of.
