[section unconstrained_set_of Views]

An unconstrained_set_of set view is a view with no constraints. The use
of these kind of view boost the bimap performance but the view can not
be accessed. An unconstrained view is an empty class.

    namespace boost {
    namespace bimaps {
    namespace views {

    template< ``['-implementation defined parameter list-]`` >
    class ``['-implementation defined view name-]``
    {
        // Empty view
    };

    } // namespace views
    } // namespace bimap
    } // namespace boost



In the case of a `bimap< unconstrained_set_of<Left>, ... >`

In the set view:

    typedef signature-compatible with relation< Left, ... > key_type;
    typedef signature-compatible with relation< Left, ... > value_type;

In the left map view:

    typedef  Left  key_type;
    typedef  ...   mapped_type;

    typedef signature-compatible with std::pair< Left, ... > value_type;

In the right map view:

    typedef  ...  key_type;
    typedef  Left mapped_type;

    typedef signature-compatible with std::pair< ... , Left > value_type;



[#unconstrained_set_of_complexity_signature]

[section Complexity signature]

We adopt the scheme outlined in the
[link complexity_signature_explanation complexity signature section].
An unconstrained view can not be accessed by the user, but the
formulas to find the order of an operation for a bimap hold with
the following definitions.
The complexity signature of a `unconstrained_set_of` view is:

* copying: `c(n) = 0`
* insertion: `i(n) = 0`
* hinted insertion: `h(n) = 0`
* deletion: `d(n) = 0`
* replacement: `r(n) = 0`
* modifying: `m(n) = 0`

[section Serialization]

Views cannot be serialized on their own, but only as part of the
`bimap` into which they are embedded. In describing the additional
preconditions and guarantees associated to `list_of` views with respect to
serialization of their embedding containers, we use the concepts defined in the
`bimap` serialization section.

[blurb [*Operation:] saving of a `bimap` b to an output archive
(XML archive) ar.]

* [*Requires:] No additional requirements to those imposed by the container.

[blurb [*Operation:] loading of a `bimap` b' from an input archive
(XML archive) ar.]

* [*Requires:] No additional requirements to those imposed by the container.
