Examples of PositionIterator

nz.ac.waikato.jdsl.core.api.PositionIterator
Iterator over a set of positions. No order of the positions is required by this interface, although order may be promised or required by users of the interface. Conceptually, the iterator starts out situated before the first position to be considered. With each call to next(), the iterator skips over another position and returns the position skipped over, until the iterator is situated past the last position. Note that NoSuchElementException indicates two different failure states: when the iterator is situated before the first position, position() and element() fail; when the iterator is situated after the last position, next() fails. @version JDSL 2.1.1 @author Mark Handy
