Method Documentation

- (void) diffusionStream: (PTDiffusionValueStream *)  stream
didUpdateTopicPath: (NSString *)  topicPath
specification: (PTDiffusionTopicSpecification *)  specification
oldBinary: (nullable PTDiffusionBinary *)  oldBinary
newBinary: (PTDiffusionBinary *)  newBinary 

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

Parameters
streamThe value stream that received the update.
topicPathThe topic path that was updated.
specificationThe specification for the updated topic.
oldBinaryThe previous value. If nil then this is the first value.
