gaps
public int gaps()
Description copied from class:IntervalIterator
The number of gaps within the current interval Note that this returns the number of gaps between the immediate sub-intervals of this interval, and does not include the gaps inside those sub-intervals. Should not be called beforeIntervalIterator.nextInterval()
