## Tree::ConstIterator Class

### Members

---

## const Node * get ( ) const

Returns iterator's node pointer.
### Return value

The const iterator's node pointer.
## ConstIterator ( )

Default constructor.
## ConstIterator ( const ConstIterator & it )

Copy constructor.
### Arguments

- *const ConstIterator &* **it** - ConstIterator.

## int operator!= ( const typename Tree < Key, Data >::Iterator & it ) const

Check if two iterators are not the same.
### Arguments

- *const typename [Tree](../../../../api/library/containers/tree/class.tree_cpp.md)< Key, Data >::Iterator &* **it** - The second iterator.

### Return value

1 if iterators are not the same; otherwise, 0.
