Public functions
FillAllocationDescription
virtual void FillAllocationDescription(
AllocationDescription *proto
) const =0
Fills metadata about the allocation into the proto.
GetAllocatedBytes
virtual bool GetAllocatedBytes(
size_t *out_bytes
) const
OwnsMemory
virtual bool OwnsMemory() const
TensorBuffer
TensorBuffer(
void *data_ptr
)
base
T * base() const
Helper method to reinterpret the buffer as an array of
T
.
data
void * data() const
data()
points to a memory region of
size()
bytes.
NOTE(mrry): The
data()
method is not virtual for performance reasons. It can be called multiple times when the contents of a
Tensor
are accessed, and so making it non-virtual allows the body to be inlined.
size
virtual size_t size() const =0
Size (in bytes) of the buffer.
