Method Documentation

- (void) diffusionStream: (PTDiffusionValueStream *)  stream
didUpdateTimeSeriesTopicPath: (NSString *)  topicPath
specification: (PTDiffusionTopicSpecification *)  specification
oldBinaryEvent: (nullable PTDiffusionBinaryTimeSeriesEvent *)  oldBinaryEvent
newBinaryEvent: (PTDiffusionBinaryTimeSeriesEvent *)  newBinaryEvent 

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

streamThe value stream that received the update.
topicPathThe topic path that was updated.
specificationThe specification for the updated topic.
oldBinaryEventThe previous event. If nil then this is the first event.
newBinaryEventThe new event derived from the last update received from the server.
