question: protected void storeState ( ) { if ( tree != null ) { System . arraycopy ( intervals , 0 , storedIntervals , 0 , intervals . length ) ; System . arraycopy ( lineageCounts , 0 , storedLineageCounts , 0 , lineageCounts . length ) ; storedIntervalsKnown = intervalsKnown ; storedIntervalCount = intervalCount ; storedLikelihoodKnown = likelihoodKnown ; } else if ( treesSet != null ) { treesSet . storeTheState ( ) ; } storedLogLikelihood = logLikelihood ; }
target:  Stores the precalculated state: in this case the intervals
