Class LongBigListIterators.AbstractIndexBasedBigListIterator

  • All Implemented Interfaces:
    BidirectionalIterator<java.lang.Long>, BigListIterator<java.lang.Long>, LongBidirectionalIterator, LongBigListIterator, LongIterator, ObjectBidirectionalIterator<java.lang.Long>, ObjectIterator<java.lang.Long>, java.util.Iterator<java.lang.Long>, java.util.PrimitiveIterator<java.lang.Long,​java.util.function.LongConsumer>, java.util.PrimitiveIterator.OfLong
    Enclosing class:
    LongBigListIterators

    public abstract static class LongBigListIterators.AbstractIndexBasedBigListIterator
    extends LongBigListIterators.AbstractIndexBasedBigIterator
    implements LongBigListIterator
    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.Long>
        Returns:
        whether there is a previous element.
        See Also:
        ListIterator.hasPrevious()
      • 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.Long>
        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.Long>
        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​(long k)
        Description copied from interface: LongBigListIterator
        Inserts the specified element into the list (optional operation).
        Specified by:
        add in interface LongBigListIterator
        See Also:
        ListIterator.add(Object)
      • set

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