Project Description

Implementation of the Observer pattern for NumPy arrays.

Example

from numpy import array
from ndarray_listener import ndarray_listener as ndl

a = ndl(array([-0.5, 0.1, 1.1]))

class Observer(object):
  def __init__(self):
    self.called_me = False

  def __call__(self, _):
    self.called_me = True

o = Observer()
a.talk_to(o)
print(o.called_me)
a[0] = 1.2
print(o.called_me)

The output should be

False
True
