Method Detail

start

public int start()

Description copied from class: IntervalIterator

The start of the current interval Returns -1 if IntervalIterator.nextInterval() has not yet been called and IntervalIterator.NO_MORE_INTERVALS once the iterator is exhausted.

Specified by:

start in class IntervalIterator

end

public int end()

Description copied from class: IntervalIterator

The end of the current interval Returns -1 if IntervalIterator.nextInterval() has not yet been called and IntervalIterator.NO_MORE_INTERVALS once the iterator is exhausted.

Specified by:

end in class IntervalIterator

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 before IntervalIterator.nextInterval(), or after it has returned IntervalIterator.NO_MORE_INTERVALS

Specified by:

gaps in class IntervalIterator

reset

protected void reset()
              throws java.io.IOException

Specified by:

reset in class ConjunctionIntervalIterator

Throws:

java.io.IOException
