Description : fast, typed, resizable, Cython array
Binary package names: python3-cyarray
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.
