    Method
    Description
    final void
    add(T linkable)
    Insert linkable at the current position of the iterator.
    final boolean
    hasNext()
    True if a call to next() will return an object.
    final boolean
    hasPrevious()
    True if a call to previous() will return a value.
    final T
    next()
    Returns the value at the Iterator's index and advances the iterator.
    final int
    nextIndex()
    returns the index of the next node in the list (the one that would be returned by a call to next()).
    final T
    previous()
    Returns the value before the Iterator's index and moves the iterator back one index.
    final int
    previousIndex()
    Returns the previous element's index.
    final void
    remove()
    Removes the current element in the list and shrinks its size accordingly.
    final void
    set(T linkable)
    Replaces the current element in the list with linkable

  • Method Details

    • add

      public final void add(T linkable)
      Insert linkable at the current position of the iterator. Calling next() after add() will return the added object.
      Specified by:
      add in interface ListIterator<T extends TLinkable<T>>
      Parameters:
      linkable - an object of type TLinkable

    • hasNext

      public final boolean hasNext()
      True if a call to next() will return an object.
      Specified by:
      hasNext in interface Iterator<T extends TLinkable<T>>
      Specified by:
      hasNext in interface ListIterator<T extends TLinkable<T>>
      Returns:
      a boolean value

    • hasPrevious

      public final boolean hasPrevious()
      True if a call to previous() will return a value.
      Specified by:
      hasPrevious in interface ListIterator<T extends TLinkable<T>>
      Returns:
      a boolean value

    • next

      public final T next()
      Returns the value at the Iterator's index and advances the iterator.
      Specified by:
      next in interface Iterator<T extends TLinkable<T>>
      Specified by:
      next in interface ListIterator<T extends TLinkable<T>>
      Returns:
      an Object value
      Throws:
      NoSuchElementException - if there is no next element

    • nextIndex

      public final int nextIndex()
      returns the index of the next node in the list (the one that would be returned by a call to next()).
      Specified by:
      nextIndex in interface ListIterator<T extends TLinkable<T>>
      Returns:
      an int value

    • previous

      public final T previous()
      Returns the value before the Iterator's index and moves the iterator back one index.
      Specified by:
      previous in interface ListIterator<T extends TLinkable<T>>
      Returns:
      an Object value
      Throws:
      NoSuchElementException - if there is no previous element.

    • previousIndex

      public final int previousIndex()
      Returns the previous element's index.
      Specified by:
      previousIndex in interface ListIterator<T extends TLinkable<T>>
      Returns:
      an int value

    • remove

      public final void remove()
      Removes the current element in the list and shrinks its size accordingly.
      Specified by:
      remove in interface Iterator<T extends TLinkable<T>>
      Specified by:
      remove in interface ListIterator<T extends TLinkable<T>>
      Throws:
      IllegalStateException - neither next nor previous have been invoked, or remove or add have been invoked after the last invocation of next or previous.

    • set

      public final void set(T linkable)
      Replaces the current element in the list with linkable
      Specified by:
      set in interface ListIterator<T extends TLinkable<T>>
      Parameters:
      linkable - an object of type TLinkable
