This operator can be use to set/update the meta data for the stream elements.


Remark: This will update the whole meta data. If you want to add an additional meta data you must also repeat the existing meta data, the existing values are retained.


timer2 = TIMER({PERIOD = 2000, TIMEFROMSTART = true, SOURCE = 'source6', METAATTRIBUTE = 'TimeInterval'})
out = SELECT({PREDICATE = 'time > 0 && TimeInterval.start > 0'},timer2)
out2a = METADATA({METAATTRIBUTE = 'TimeIntervalLatencyDatarate'},out)
out2b = METADATA({METAATTRIBUTE = ['TimeInterval','Latency','Datarate']},out)
