Class ObjectIterators.AbstractIndexBasedListIterator<K>
- All Implemented Interfaces:
BidirectionalIterator<K>,ObjectBidirectionalIterator<K>,ObjectIterator<K>,ObjectListIterator<K>,Iterator<K>,ListIterator<K>
- Enclosing class:
ObjectIterators
This class is only appropriate for sequences that are at most Integer.MAX_VALUE long. If
your backing data store can be bigger then this, consider the equivalently named class in the
type specific BigListSpliterators class.
As the abstract methods in this class are used in inner loops, it is generally a good idea to
override the class as final as to encourage the JVM to inline them (or alternatively,
override the abstract methods as final).

Method Details
-
hasPrevious
public boolean hasPrevious()Description copied from interface:BidirectionalIteratorReturns whether there is a previous element.- Specified by:
hasPreviousin interfaceBidirectionalIterator<K>- Specified by:
hasPreviousin interfaceListIterator<K>- Returns:
- whether there is a previous element.
- See Also:
-
previous
Description copied from interface:BidirectionalIteratorReturns the previous element from the collection.- Specified by:
previousin interfaceBidirectionalIterator<K>- Specified by:
previousin interfaceListIterator<K>- Returns:
- the previous element from the collection.
- See Also:
-
nextIndex
public int nextIndex()- Specified by:
nextIndexin interfaceListIterator<K>
-
previousIndex
public int previousIndex()- Specified by:
previousIndexin interfaceListIterator<K>
-
add
Description copied from interface:ObjectListIteratorInserts the specified element into the list (optional operation).This default implementation just throws an
UnsupportedOperationException.- Specified by:
addin interfaceListIterator<K>- Specified by:
addin interfaceObjectListIterator<K>- Parameters:
k- the element to insert.- See Also:
-
set
Description copied from interface:ObjectListIteratorReplaces the last element returned byIterator.next()orBidirectionalIterator.previous()with the specified element (optional operation).- Specified by:
setin interfaceListIterator<K>- Specified by:
setin interfaceObjectListIterator<K>- Parameters:
k- the element used to replace the last element returned.This default implementation just throws an
UnsupportedOperationException.- See Also:
-
back
public int back(int n) Description copied from interface:ObjectBidirectionalIteratorMoves back for the given number of elements.The effect of this call is exactly the same as that of calling
BidirectionalIterator.previous()forntimes (possibly stopping ifBidirectionalIterator.hasPrevious()becomes false).- Specified by:
backin interfaceObjectBidirectionalIterator<K>- Parameters:
n- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
