cfdm.RaggedContiguousArray

---

class cfdm.RaggedContiguousArray(compressed_array=None, shape=None, size=None, ndim=None, count_variable=None)

Bases: cfdm.data.mixin.raggedcontiguous.RaggedContiguous, cfdm.data.abstract.compressedarray.CompressedArray

An underlying contiguous ragged array.

A collection of features stored using a contiguous ragged array combines all features along a single dimension (the “sample dimension”) such that each feature in the collection occupies a contiguous block.

The information needed to uncompress the data is stored in a “count variable” that gives the size of each block.

It is assumed that the compressed dimension is the left-most dimension in the compressed array.

New in version (cfdm): 1.7.0

Initialisation

Parameters

compressed_array: Data

The compressed data.

shape: tuple

The uncompressed array dimension sizes.

size: int

Number of elements in the uncompressed array.

ndim: int

The number of uncompressed array dimensions

count_variable: Count

The count variable required to uncompress the data, corresponding to a CF-netCDF count variable.

Inspection

Methods

get_compressed_axes	Return axes that are compressed in the underlying array.
get_compressed_dimension	Returns the compressed dimension’s position in the array.
get_compression_type	Returns the array’s compression type.
get_count	Return the count variable for a compressed array.

Attributes

array	Returns a numpy array containing the uncompressed data.
compressed_array	Returns an independent numpy array with the compressed data.
dtype	Data-type of the data elements.
ndim	The number of dimensions of the uncompressed data.
shape	Shape of the uncompressed data.
