Part of twisted.flow.wrap View Source View In Hierarchy
Wraps a Deferred object into a stage; create with flow.wrapThis 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||_yield||executed during a yield statement by previous stage|
Inherited from Stage:
|Method||next||return current result|
executed during a yield statement by previous stageThis 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.
