hasPrevious
public boolean hasPrevious()
Description copied from interface:BidirectionalIterator
Returns whether there is a previous element.- Specified by:
hasPrevious
in interfaceBidirectionalIterator<Integer>
- Returns:
- whether there is a previous element.
- See Also:
ListIterator.hasPrevious()
-
nextInt
public int nextInt()
Description copied from interface:IntIterator
Returns the next element as a primitive type.- Specified by:
nextInt
in interfaceIntIterator
- Specified by:
nextInt
in interfacePrimitiveIterator.OfInt
- Returns:
- the next element in the iteration.
- See Also:
Iterator.next()
-
previousInt
public int previousInt()
Description copied from interface:IntBidirectionalIterator
Returns the previous element as a primitive type.- Specified by:
previousInt
in interfaceIntBidirectionalIterator
- Returns:
- the previous element in the iteration.
- 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<Integer>
- 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<Integer>
- 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:IntBigListIterator
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 interfaceIntBigListIterator
- 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:IntBigListIterator
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 interfaceIntBigListIterator
- Parameters:
n
- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
- See Also:
BidirectionalIterator.previous()
