◆ Allocate()

void Allocate ( )

◆ Deallocate()

void Deallocate ( )

Deallocate memory.

◆ 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.
