it.unimi.dsi.fastutil.objects.ObjectBigListIterators.EmptyBigListIterator<K>
All Implemented Interfaces:
BidirectionalIterator<K>, BigListIterator<K>, ObjectBidirectionalIterator<K>, ObjectBigListIterator<K>, ObjectIterator<K>, java.io.Serializable, java.lang.Cloneable, java.util.Iterator<K>
Enclosing class:
ObjectBigListIterators
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 Details

    • hasNext

      public boolean hasNext()
      Specified by:
      hasNext in interface java.util.Iterator<K>

    • hasPrevious

      public boolean hasPrevious()
      Description copied from interface: BidirectionalIterator
      Returns whether there is a previous element.
      Specified by:
      hasPrevious in interface BidirectionalIterator<K>
      Returns:
      whether there is a previous element.
      See Also:
      ListIterator.hasPrevious()

    • next

      public K next()
      Specified by:
      next in interface java.util.Iterator<K>

    • previous

      public K previous()
      Description copied from interface: BidirectionalIterator
      Returns the previous element from the collection.
      Specified by:
      previous in interface BidirectionalIterator<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 interface BigListIterator<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 interface BigListIterator<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() for n times (possibly stopping if Iterator.hasNext() becomes false).

      Specified by:
      skip in interface ObjectBigListIterator<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() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

      Specified by:
      back in interface ObjectBigListIterator<K>
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      BidirectionalIterator.previous()

    • clone

      public java.lang.Object clone()

    • forEachRemaining

      public void forEachRemaining​(java.util.function.Consumer<? super K> action)
      Specified by:
      forEachRemaining in interface java.util.Iterator<K>
