Description

The scope list provides a read-only access to a doubly-linked list of scopes.

`named_scope_list` public types

typedef implementation_defined const_iterator;

A constant iterator to the sequence of scopes. Complies to bidirectional iterator requirements.
typedef implementation_defined iterator;

An iterator to the sequence of scopes. Complies to bidirectional iterator requirements.
typedef implementation_defined const_reverse_iterator;

A constant reverse iterator to the sequence of scopes. Complies to bidirectional iterator requirements.
typedef implementation_defined reverse_iterator;

A reverse iterator to the sequence of scopes. Complies to bidirectional iterator requirements.

`named_scope_list` public construct/copy/destruct

```
named_scope_list();
```
Default constructor

Postconditions:

empty() == true
```
named_scope_list(named_scope_list const & that);
```
Copy constructor

Postconditions:

std::equal(begin(), end(), that.begin()) == true
```
named_scope_list & operator=(named_scope_list const & that);
```
Assignment operator

Postconditions:

std::equal(begin(), end(), that.begin()) == true
```
~named_scope_list();
```
Destructor. Destroys the stored entries.

`named_scope_list` public member functions

```
const_iterator begin() const;
```
Returns:

Constant iterator to the first element of the container.
```
const_iterator end() const;
```
Returns:

Constant iterator to the after-the-last element of the container.
```
const_reverse_iterator rbegin() const;
```
Returns:

Constant iterator to the last element of the container.
```
const_reverse_iterator rend() const;
```
Returns:

Constant iterator to the before-the-first element of the container.
```
size_type size() const;
```
Returns:

The number of elements in the container
```
bool empty() const;
```
Returns:

true if the container is empty and false otherwise
```
void swap(named_scope_list & that);
```
Swaps two instances of the container
```
const_reference back() const;
```
Returns:

Last pushed scope entry
```
const_reference front() const;
```
Returns:

First pushed scope entry
