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 |
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.
