      • assign

        public void assign​(IteratorSTL<T> otherIterator)
        Description copied from interface: IteratorSTL
        'Assigns' this iterator to be equivalent to the given iterator. This is equivalent to C++'s '=' overloading mechanism
        Specified by:
        assign in interface IteratorSTL<T>
        Parameters:
        otherIterator - The iterator to copy

      • 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.

      • 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.

      • 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

      • get

        public T get​(int offset)

      • decrement

        public IteratorSTL<T> decrement()
        Description copied from interface: IteratorSTL

        decrement in interface IteratorSTL<T>
        Returns:
        a reference to the iterator itself

      • 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

      • increment

        Description copied from interface: IteratorSTL
        Advances the iterator n positions.
        Specified by:
        increment in interface IteratorSTL<T>
        Returns:
        a reference to the iterator itself
