    • 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
      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

    • 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

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

    • decrement

      public IteratorSTL<T> decrement​(int count)
      Description copied from interface: IteratorSTL
      Devances the iterator n positions.
      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.
