isNeverEnding
public boolean isNeverEnding()Description copied from interface:Selector
Is true ifSelector.isCountable()
is false or if this selector is in random order (for most cases). Is never true when this selector is in shuffled order (which is less scalable but more exact).- Returns:
- true if the
Iterator.hasNext()
of theIterator
created byIterable.iterator()
never returns false (except when it's empty).
