Class t.f.w._Deferred(Stage):

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.

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.
