Method Documentation

diffusionStream:didUpdateTimeSeriesTopicPath:specification:oldNumberEvent:newNumberEvent:

- (void) diffusionStream:		(PTDiffusionValueStream *)	stream
didUpdateTimeSeriesTopicPath:		(NSString *)	topicPath
specification:		(PTDiffusionTopicSpecification *)	specification
oldNumberEvent:		(nullable PTDiffusionNumberTimeSeriesEvent *)	oldNumberEvent
newNumberEvent:		(PTDiffusionNumberTimeSeriesEvent *)	newNumberEvent

An update was received for a topic path handled by a binary value stream.

Parameters

stream	The value stream that received the update.
topicPath	The topic path that was updated.
specification	The specification for the updated topic.
oldNumberEvent	The previous event. If nil then this is the first event.
newNumberEvent	The new event derived from the last update received from the server.
