diffusionStream:didUpdateTopicPath:specification:oldBinary:newBinary:

- (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

stream	The value stream that received the update.
topicPath	The topic path that was updated.
specification	The specification for the updated topic.
oldBinary	The previous value. If nil then this is the first value.
