Introduction

What is python3-cyarray
python3-cyarray is:
The cyarray package provides a fast, typed, re-sizable, Cython array.
It currently provides the following arrays: IntArray, UIntArray, LongArray, FloatArray, DoubleArray
.
All arrays provide for the following operations:
- access by indexing.
- access through get/set function.
- resizing the array.
- appending values at the end of the array.
- reserving space for future appends.
- access to internal data through a numpy array.
If you are writing Cython code this is a convenient array to use as it
exposes the raw underlying pointer to the data.
For example if you use a FloatArray
and access its data
attribute it will be a float*
.
Each array also provides an interface to its data through a numpy
array.
This is done through the get_npy_array
function.
The returned numpy array can be used just like any other numpy array
but for the following restrictions:
- the array may not be resized.
- references of this array should not be kept.
- slices of this array may not be made.
The numpy array may however be copied and used in any manner.
