Class IntBigListIterators.AbstractIndexBasedBigListIterator

  • All Implemented Interfaces:
    BidirectionalIterator<java.lang.Integer>, BigListIterator<java.lang.Integer>, IntBidirectionalIterator, IntBigListIterator, IntIterator, ObjectBidirectionalIterator<java.lang.Integer>, ObjectIterator<java.lang.Integer>, java.util.Iterator<java.lang.Integer>, java.util.PrimitiveIterator<java.lang.Integer,​java.util.function.IntConsumer>, java.util.PrimitiveIterator.OfInt
    Enclosing class:
    IntBigListIterators

    public abstract static class IntBigListIterators.AbstractIndexBasedBigListIterator
    extends IntBigListIterators.AbstractIndexBasedBigIterator
    implements IntBigListIterator
    A skeletal implementation for a list-iterator backed by an index based data store. High performance concrete implementations (like the main ListIterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.

    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).

      • hasPrevious

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

        public int previousInt()
        Description copied from interface: IntBidirectionalIterator
        Returns the previous element as a primitive type.
        Specified by:
        previousInt in interface IntBidirectionalIterator
        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 interface BigListIterator<java.lang.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 interface BigListIterator<java.lang.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()
      • add

        public void add​(int k)
        Description copied from interface: IntBigListIterator
        Inserts the specified element into the list (optional operation).
        Specified by:
        add in interface IntBigListIterator
        See Also:
        ListIterator.add(Object)
      • set

        public void set​(int k)
        Description copied from interface: IntBigListIterator
        Replaces the last element returned by next() or previous() with the specified element (optional operation).
        Specified by:
        set in interface IntBigListIterator
        See Also:
        ListIterator.set(Object)
