    • Method Summary

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

      • 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 java.util.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 java.util.Iterator<T extends TLinkable<T>>
        Specified by:
        hasNext in interface java.util.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 java.util.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 java.util.Iterator<T extends TLinkable<T>>
        Specified by:
        next in interface java.util.ListIterator<T extends TLinkable<T>>
        Returns:
        an Object value
        Throws:
        java.util.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 java.util.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 java.util.ListIterator<T extends TLinkable<T>>
        Returns:
        an Object value
        Throws:
        java.util.NoSuchElementException - if there is no previous element.

      • previousIndex

        public final int previousIndex()
        Returns the previous element's index.
        Specified by:
        previousIndex in interface java.util.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 java.util.ListIterator<T extends TLinkable<T>>
        Throws:
        java.lang.IllegalStateException - neither next nor previous have been invoked, or remove or add have been invoked after the last invocation of next or previous.
