        public IteratorSTL<T> copy()
        Description copied from interface: IteratorSTL
        Creates a copy of this iterator.
        Specified by:
        copy in interface IteratorSTL<T>
        Returns:
        a copy of this iterator.

      • delete

        public void delete()

      • delete

        public void delete​(int count)

      • get

        public T get()
        Description copied from interface: IteratorSTL
        Returns the current value of the iterator.
        Specified by:
        get in interface IteratorSTL<T>
        Returns:
        the current value of the iterator.

      • increment

        public IteratorSTL<T> increment()
        Description copied from interface: IteratorSTL
        Advances the iterator to the next position.
        Specified by:
        increment in interface IteratorSTL<T>
        Returns:
        a reference to the iterator itself

      • decrement

        public IteratorSTL<T> decrement()
        Description copied from interface: IteratorSTL
        Devance the iterator to the previous position. This method is only supported in bidirectional iterators.
        Specified by:
        decrement in interface IteratorSTL<T>
        Returns:
        a reference to the iterator itself

      • insert

        public void insert​(T value)
        Description copied from interface: IteratorSTL
        Inserts the given value at the current position (the current value will be pushed to the next value). The iterator will be positioned on the new value.
        Specified by:
        insert in interface IteratorSTL<T>
        Parameters:
        value - the value to insert into the collection.

      • isBegin

        public boolean isBegin()
        Description copied from interface: IteratorSTL
        Returns true if the iterator is positioned on the first first element of the collection. If the collection is empty, this will always return false.
        Specified by:
        isBegin in interface IteratorSTL<T>
        Returns:
        true if the iterator is positioned on the first element of the collection.

      • isEnd

        public boolean isEnd()
        Description copied from interface: IteratorSTL
        Returns true if the iterator is positioned past the last element of the collection. If the collection is empty, this will always return true.
        Specified by:
        isEnd in interface IteratorSTL<T>
        Returns:
        true if the iterator is positioned past the last element of the collection.

      • set

        public void set​(T value)
        Description copied from interface: IteratorSTL
        Sets the current value of the iterator to the given value.
        Specified by:
        set in interface IteratorSTL<T>
        Parameters:
        value - the value to set at the iterator position

      • decrement

        public IteratorSTL<T> decrement​(int n)
        Description copied from interface: IteratorSTL
        Devances the iterator n positions.
        Specified by:
        decrement in interface IteratorSTL<T>
        Returns:
        a reference to the iterator itself

      • increment

        public IteratorSTL<T> increment​(int n)
        Description copied from interface: IteratorSTL
        Advances the iterator n positions.
        Specified by:
