public static class ObjectBigListIterators.EmptyBigListIterator<K> extends java.lang.Object implements ObjectBigListIterator<K>, java.io.Serializable, java.lang.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 Detail
-
hasNext
public boolean hasNext()
- Specified by:
hasNext
in interfacejava.util.Iterator<K>
-
hasPrevious
public boolean hasPrevious()
Description copied from interface:BidirectionalIterator
Returns whether there is a previous element.- Specified by:
hasPrevious
in interfaceBidirectionalIterator<K>
- Returns:
- whether there is a previous element.
- See Also:
ListIterator.hasPrevious()
-
previous
public K previous()
Description copied from interface:BidirectionalIterator
Returns the previous element from the collection.- Specified by:
previous
in interfaceBidirectionalIterator<K>
- Returns:
- the previous element from the collection.
- See Also:
ListIterator.previous()
-
nextIndex
public long nextIndex()
Description copied from interface:BigListIterator
Returns 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:
nextIndex
in 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:
ListIterator.nextIndex()
-
previousIndex
public long previousIndex()
Description copied from interface:BigListIterator
Returns 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:
previousIndex
in 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:
ListIterator.previousIndex()
-
skip
public long skip(long n)
Description copied from interface:ObjectBigListIterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling
next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Specified by:
skip
in interfaceObjectBigListIterator<K>
- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
Iterator.next()
-
back
public long back(long n)
Description copied from interface:ObjectBigListIterator
Moves back for the given number of elements.The effect of this call is exactly the same as that of calling
previous()
forn
times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceObjectBigListIterator<K>
- Parameters:
n
- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
