blinker 1.2 : Python Package Index
Fast, simple object-to-object and broadcast signaling
Blinker provides a fast dispatching system that allows any number of
interested parties to subscribe to events, or "signals".Signal receivers can subscribe to specific senders or receive signals
sent by any sender.>>> from blinker import signal >>> started = signal('round-started') >>> def each(round): ... print "Round %s!" % round ... >>> started.connect(each)>>> def round_two(round): ... print "This is round two." ... >>> started.connect(round_two, sender=2)>>> for round in range(1, 4): ... started.send(round) ... Round 1! Round 2! This is round two. Round 3!Requirements
Blinker requires Python 2.4 or higher, Python 3.0 or higher, or Jython 2.5 or higher.
