Class DoubleBigListIterators.AbstractIndexBasedBigListIterator

java.lang.Object
All Implemented Interfaces:
BidirectionalIterator<java.lang.Double>, BigListIterator<java.lang.Double>, DoubleBidirectionalIterator, DoubleBigListIterator, DoubleIterator, ObjectBidirectionalIterator<java.lang.Double>, ObjectIterator<java.lang.Double>, java.util.Iterator<java.lang.Double>, java.util.PrimitiveIterator<java.lang.Double,​java.util.function.DoubleConsumer>, java.util.PrimitiveIterator.OfDouble
Enclosing class:
DoubleBigListIterators

public abstract static class DoubleBigListIterators.AbstractIndexBasedBigListIterator
extends DoubleBigListIterators.AbstractIndexBasedBigIterator
implements DoubleBigListIterator
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.Double>
      Returns:
      whether there is a previous element.
      See Also:
      ListIterator.hasPrevious()
    • previousDouble

      public double previousDouble()
      Description copied from interface: DoubleBidirectionalIterator
      Returns the previous element as a primitive type.
      Specified by:
      previousDouble in interface DoubleBidirectionalIterator
      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.Double>
      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.Double>
      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​(double k)
      Description copied from interface: DoubleBigListIterator
      Inserts the specified element into the list (optional operation).
      Specified by:
      add in interface DoubleBigListIterator
      See Also:
      ListIterator.add(Object)
    • set

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

      public long back​(long n)
      Description copied from interface: DoubleBigListIterator
      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 DoubleBigListIterator
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      BidirectionalIterator.previous()
