pyarrow.Buffer — Apache Arrow v20.0.0

class pyarrow.Buffer#

Bases: _Weakrefable

The base class for all Arrow buffers.

A buffer represents a contiguous memory area. Many buffers will own their memory, though not all of them do.

__init__(*args, **kwargs)#

Methods

Attributes

address#

The buffer’s address, as an integer.

The returned address may point to CPU or device memory. Use is_cpu() to disambiguate.

device#

The device where the buffer resides.

Returns:

Device

device_type#

The device type where the buffer resides.

Returns:

DeviceAllocationType

equals(self, Buffer other)#

Determine if two buffers contain exactly the same data.

Parameters:

otherBuffer

Returns:

are_equalbool

True if buffer contents and size are equal

hex(self)#

Compute hexadecimal representation of the buffer.

Returns:

: bytes

is_cpu#

Whether the buffer is CPU-accessible.

is_mutable#

Whether the buffer is mutable.

memory_manager#

The memory manager associated with the buffer.

Returns:

MemoryManager

parent#

size#

The buffer size in bytes.

slice(self, offset=0, length=None)#

Slice this buffer. Memory is not copied.

You can also use the Python slice notation buffer[start:stop].

Parameters:

offsetint, default 0

Offset from start of buffer to slice.

lengthint, default None

Length of slice (default is until end of Buffer starting from offset).

Returns:

slicedBuffer

A logical view over this buffer.

to_pybytes(self)#

Return this buffer as a Python bytes object. Memory is copied.
