- Class ``ptr_set_adapter``
- -------------------------
- This class is used to build custom pointer containers with
- an underlying set-like container. The interface of the class is an extension
- of the interface from ``associative_ptr_container``.

- Semantics
- ---------
- .. _`modifiers`:
- Semantics: modifiers
- ^^^^^^^^^^^^^^^^^^^^
- - ``std::pair<iterator,bool> insert( key_type* x );``
- - Requirements: ``x != 0``
- - Effects: Takes ownership of ``x`` and insert it if there is no equivalent of it already. The ``bool`` part of the return value indicates insertion and the iterator points to the element with key ``x``.
- - Throws: bad_pointer if ``x == 0``
- - Exception safety: Strong guarantee
-
- - ``template< class Key2 > std::pair<iterator,bool> insert( compatible-smart-ptr<Key2> x );``
- - Effects: ``return insert( x.release() );``
- ..
- - ``std::pair<iterator,bool> insert( const key_type& x );``
- - Effects: ``return insert( allocate_clone( x ) );``
- - Exception safety: Strong guarantee
- .. _`pointer container requirements`:
- Semantics: pointer container requirements
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- - ``bool transfer( iterator object, ptr_set_adapter& from );``
- - Requirements: ``not from.empty()``
- - Effects: Inserts the object defined by ``object`` into the container and remove it from ``from``
- iff no equivalent object exists.
- - Returns: whether the object was transfered
-
- - Exception safety: Strong guarantee
- - ``void transfer( iterator first, iterator last, ptr__set_adapter& from );``
- - Requirements: ``not from.empty()``
- - Effects: Inserts the objects defined by the range ``[first,last)`` into the container and remove it from ``from``.
- An object is only transferred if no equivalent object exists.
- - Returns: the number of transfered objects
-
- - Exception safety: Basic guarantee
- - ``template< class Range > void transfer( const Range& r, ptr_set_adapter& from );``
- - Effects: ``return transfer( boost::begin(r), boost::end(r), from );``
-
- - ``size_type transfer( ptr_set_adapter& from );``
- - Effects: ``return transfer( from.begin(), from.end(), from );``.
