Class LongIterators.AbstractIndexBasedListIterator
- All Implemented Interfaces:
BidirectionalIterator<Long>,LongBidirectionalIterator,LongIterator,LongListIterator,ObjectBidirectionalIterator<Long>,ObjectIterator<Long>,Iterator<Long>,ListIterator<Long>,PrimitiveIterator<Long, LongConsumer>,PrimitiveIterator.OfLong
- Enclosing class:
LongIterators
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<Long>- Specified by:
hasPreviousin interfaceListIterator<Long>- Returns:
- whether there is a previous element.
- See Also:
-
previousLong
public long previousLong()Description copied from interface:LongBidirectionalIteratorReturns the previous element as a primitive type.- Specified by:
previousLongin interfaceLongBidirectionalIterator- Returns:
- the previous element in the iteration.
- See Also:
-
nextIndex
public int nextIndex()- Specified by:
nextIndexin interfaceListIterator<Long>
-
previousIndex
public int previousIndex()- Specified by:
previousIndexin interfaceListIterator<Long>
-
add
public void add(long k) Description copied from interface:LongListIteratorInserts the specified element into the list (optional operation).This default implementation just throws an
UnsupportedOperationException.- Specified by:
addin interfaceLongListIterator- Parameters:
k- the element to insert.- See Also:
-
set
public void set(long k) Description copied from interface:LongListIteratorReplaces the last element returned byLongListIterator.next()orLongListIterator.previous()with the specified element (optional operation).- Specified by:
setin interfaceLongListIterator- 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:LongBidirectionalIteratorMoves back for the given number of elements.The effect of this call is exactly the same as that of calling
LongBidirectionalIterator.previous()forntimes (possibly stopping ifBidirectionalIterator.hasPrevious()becomes false).- Specified by:
backin interfaceLongBidirectionalIterator- Specified by:
backin interfaceObjectBidirectionalIterator<Long>- Parameters:
n- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
