Funzioni pubbliche
FillAllocationDescription
virtual void FillAllocationDescription(
AllocationDescription *proto
) const =0
Compila i metadati relativi all'allocazione nel proto.
Ottieni byte allocati
virtual bool GetAllocatedBytes(
size_t *out_bytes
) const
Possiede memoria
virtual bool OwnsMemory() const
TensorBuffer
TensorBuffer(
void *data_ptr
)
base
T * base() const
Metodo helper per reinterpretare il buffer come un array di T .
dati
void * data() const
data() punta a una regione di memoria di size() byte.
NOTA(scusa): il metodo data() non è virtuale per motivi di prestazioni. Può essere chiamato più volte quando si accede al contenuto di un Tensor , quindi renderlo non virtuale consente di incorporare il corpo.
misurare
virtual size_t size() const =0
Dimensione (in byte) del buffer.
~TensorBuffer
~TensorBuffer() override
