cpyquickhelper.examples

There is no particular purpose to this examples except testing some assumptions. The first class introduces a C container which holds a void pointer.

cpyquickhelper.examples.custom_container_python.ContainerType (self, value)

Type enumeration, similar to dtype.

Members:

VOID : untyped pointer

BYTE : byte pointer

FLOAT : float pointer

DOUBLE : double pointer

INT64 : int64 pointer

cpyquickhelper.examples.custom_container_python.PyCContainer

Custom container, may contain almost everything.

The following example is a way to get the sequence of bytes for a sequence of doubles.

<<<

import numpy
from cpyquickhelper.examples.custom_container_python import PyCContainer

arr = numpy.array([0, 2, 8, 8e-2, 1], dtype=numpy.float32)
cc = PyCContainer(arr)
print(cc.dtype)
print(cc.size)
content = [cc[i] for i in range(cc.size)]
print(content)

>>>

    ContainerType.FLOAT
    20
    [0, 0, 0, 0, 0, 0, 0, 64, 0, 0, 0, 65, 10, 215, 163, 61, 0, 0, 128, 63]
