getOrCreateTimeSeries
public LongCumulative.NoopLongCumulative.NoopLongPoint getOrCreateTimeSeries(List<LabelValue> labelValues) Description copied from class:LongCumulative
Creates aTimeSeries
and returns aLongPoint
if the specifiedlabelValues
is not already associated with this cumulative, else returns an existingLongPoint
.It is recommended to keep a reference to the LongPoint instead of always calling this method for manual operations.

.- Returns:
- a
LongPoint
the value of single cumulative.
-
