Method Documentation

- (void) diffusionStream: (PTDiffusionValueStream *)  stream
didUpdateTimeSeriesTopicPath: (NSString *)  topicPath
specification: (PTDiffusionTopicSpecification *)  specification
oldRecordEvent: (nullable PTDiffusionRecordV2TimeSeriesEvent *)  oldRecordEvent
newRecordEvent: (PTDiffusionRecordV2TimeSeriesEvent *)  newRecordEvent
