pyarrow.cuda.HostBuffer#
- class pyarrow.cuda.HostBuffer#
Bases:
Buffer
Device-accessible CPU memory created using cudaHostAlloc.
To create a HostBuffer instance, use
cuda.new_host_buffer(<nbytes>)
- __init__(*args, **kwargs)#
Methods
__init__
(*args, **kwargs)equals
(self, Buffer other)Determine if two buffers contain exactly the same data.
hex
(self)Compute hexadecimal representation of the buffer.
slice
(self[, offset, length])Slice this buffer.
to_pybytes
(self)Return this buffer as a Python bytes object.
Attributes
The buffer's address, as an integer.
Whether the buffer is CPU-accessible.
Whether the buffer is mutable.
- address#
The buffer’s address, as an integer.
The returned address may point to CPU or device memory. Use is_cpu() to disambiguate.
- equals(self, Buffer other)#
Determine if two buffers contain exactly the same data.
- Parameters:
- other
Buffer
- other
- Returns:
- are_equalbool
True if buffer contents and size are equal
- is_cpu#
Whether the buffer is CPU-accessible.
- is_mutable#
Whether the buffer is mutable.
- parent#
- size#
- slice(self, offset=0, length=None)#
Slice this buffer. Memory is not copied.
You can also use the Python slice notation
buffer[start:stop]
.
- to_pybytes(self)#
Return this buffer as a Python bytes object. Memory is copied.
