boost::unordered::node_handle_set —
An object that owns a single element extracted from an
unordered_set or an
unordered_multiset, that
can then be inserted into a compatible container type.
<notes>
The name and template parameters of this type is implementation
defined, and should be obtained using the
In this version of Boost, node_type
member typedef from the appropriate container.
node_type
is different
for unordered_set
and unordered_multiset
, this will be fixed in a future version of Boost.
