t.f.w._Deferred(Stage) : class documentation

Part of twisted.flow.wrap View Source View In Hierarchy

Wraps a Deferred object into a stage; create with flow.wrap

This stage provides a callback 'catch' for errback and callbacks. If not called, then this returns an Instruction which will let the reactor execute other operations, such as the producer for this deferred.
Method __init__ Undocumented
Method _callback Undocumented
Method _errback Undocumented
Method _yield executed during a yield statement by previous stage

Inherited from Stage:

Method __iter__ Undocumented
Method next return current result
def __init__(self, deferred, *trap): (source)
Undocumented
def _callback(self, res): (source)
Undocumented
def _errback(self, fail): (source)
Undocumented
def _yield(self): (source)

executed during a yield statement by previous stage

This method is private within the scope of the flow module, it is used by one stage in the flow to ask a subsequent stage to produce its value. The result of the yield is then stored in self.result and is an instance of Failure if a problem occurred.
