java.lang.Object
it.unimi.dsi.fastutil.objects.ObjectBigListIterators.EmptyBigListIterator<K>
- All Implemented Interfaces:
BidirectionalIterator<K>, BigListIterator<K>, ObjectBidirectionalIterator<K>, ObjectBigListIterator<K>, ObjectIterator<K>, Serializable, Cloneable, Iterator<K>
- Enclosing class:
ObjectBigListIterators
public static class ObjectBigListIterators.EmptyBigListIterator<K>
extends Object
implements ObjectBigListIterator<K>, Serializable, Cloneable
A class returning no elements and a type-specific big list iterator interface.
This class may be useful to implement your own in case you subclass a type-specific iterator.

Method Details
-
hasNext
-
hasPrevious
public boolean hasPrevious()Description copied from interface:BidirectionalIteratorReturns whether there is a previous element.- Specified by:
hasPreviousin interfaceBidirectionalIterator<K>- Returns:
- whether there is a previous element.
- See Also:
-
next
-
previous
Description copied from interface:BidirectionalIteratorReturns the previous element from the collection.- Specified by:
previousin interfaceBidirectionalIterator<K>- Returns:
- the previous element from the collection.
- See Also:
-
nextIndex
public long nextIndex()Description copied from interface:BigListIteratorReturns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.)- Specified by:
nextIndexin interfaceBigListIterator<K>- Returns:
- the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of list.
- See Also:
-
previousIndex
public long previousIndex()Description copied from interface:BigListIteratorReturns the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the list iterator is at the beginning of the list.)- Specified by:
previousIndexin interfaceBigListIterator<K>- Returns:
- the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.
- See Also:
-
skip
public long skip(long n) Description copied from interface:ObjectBigListIteratorSkips the given number of elements.The effect of this call is exactly the same as that of calling
next()forntimes (possibly stopping ifIterator.hasNext()becomes false).- Specified by:
skipin interfaceObjectBigListIterator<K>- Parameters:
n- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
-
back
public long back(long n) Description copied from interface:ObjectBigListIteratorMoves back for the given number of elements.The effect of this call is exactly the same as that of calling
previous()forntimes (possibly stopping ifBidirectionalIterator.hasPrevious()becomes false).- Specified by:
backin interfaceObjectBigListIterator<K>- Parameters:
n- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
