SimpleProxy

Simple proxy for a NumPy array (or similar) that can be used with the Blosc2 compute engine.

This only supports the __getitem__ method. No caching is performed.

class blosc2.SimpleProxy(src, chunks: tuple | None = None, blocks: tuple | None = None)

Simple proxy for a NumPy array (or similar) that can be used with the Blosc2 compute engine.

This only supports the __getitem__ method. No caching is performed.

Examples

>>> import numpy as np
>>> import blosc2
>>> a = np.arange(20, dtype=np.float32).reshape(4, 5)
>>> proxy = blosc2.SimpleProxy(a)
>>> proxy[1:3, 2:4]
[[ 7.  8.]
 [12. 13.]]

Attributes:

dtype

The data type of the source array.

shape

The shape of the source array.

src

The source object that this proxy wraps.

Special Methods:

__init__(src[, chunks, blocks])
__getitem__(item)	Get a slice as a numpy.ndarray (via this proxy).

Constructor

__init__(src, chunks: tuple | None = None, blocks: tuple | None = None)

Utility Methods

__getitem__(item: slice | list[slice]) → ndarray

Get a slice as a numpy.ndarray (via this proxy).

Parameters:

item

Returns:

out – An array with the data slice.

Return type:

numpy.ndarray

property dtype

The data type of the source array.

property shape

The shape of the source array.

property src

The source object that this proxy wraps.
