Signals
|
|
=======
|
|
|
|
Mitogen exposes a simplistic signal mechanism to help decouple its internal
|
|
components. When a signal is fired by a particular instance of a class, any
|
|
functions registered to receive it will be called back.
|
|
|
|
|
|
Functions
|
|
---------
|
|
|
|
.. function:: mitogen.core.listen (obj, name, func)
|
|
|
|
Arrange for `func(\*args, \*\*kwargs)` to be invoked when the named signal
|
|
is fired by `obj`.
|
|
|
|
.. function:: mitogen.core.fire (obj, name, \*args, \*\*kwargs)
|
|
|
|
Arrange for `func(\*args, \*\*kwargs)` to be invoked for every function
|
|
registered for the named signal on `obj`.
|
|
|
|
|
|
|
