Function Details

fail(result=None)

source code

see twisted.internet.defer.fail. The biggest difference is that the twisted API allows you to call this without any parameters, which leads to an error. See http://twistedmatrix.com/trac/ticket/3145.

Returns: Deferred

deferred_accumulator(invocation_hint, return_accu, handler_return)

source code

Accumulator to use with gobject signals where callbacks are supposed to return a Deferred. With this, emit() will return a list of all the Deferred returned by the connected callbacks. It ignores callback return values that are not Deferreds.

Parameters:

invocation_hint (tuple) - (signal_id, detail, run_type) (this parameter is ignored)
return_accu (list) - a list of Deferred (or possibly None)
handler_return (elisa.core.utils.Deferred) - The return value of the signal handler

Returns: tuple

a tuple containing True and a list of deferreds.
