Fungsi publik
IsiAllokasiDeskripsi
virtual void FillAllocationDescription(
AllocationDescription *proto
) const =0
Mengisi metadata tentang alokasi ke dalam proto.
DapatkanAllocationBytes
virtual bool GetAllocatedBytes(
size_t *out_bytes
) const
Memori Milik
virtual bool OwnsMemory() const
TensorBuffer
TensorBuffer(
void *data_ptr
)
basis
T * base() const
Metode pembantu untuk menafsirkan ulang buffer sebagai array T .
data
void * data() const
data() menunjuk ke wilayah memori size() byte.
CATATAN(mrry): Metode data() bukan virtual karena alasan kinerja. Ini dapat dipanggil beberapa kali ketika konten Tensor diakses, sehingga menjadikannya non-virtual memungkinkan isi Tensor disejajarkan.
ukuran
virtual size_t size() const =0
Ukuran (dalam byte) buffer.
