\fBTemplate Parameters:\fP
.RS 4
\fI_Key\fP Type of key objects\&.

\fI_Compare\fP Comparison function object type, defaults to less<_Key>\&.

.RE
.PP
Meets the requirements of a \fCcontainer\fP, a \fCreversible container\fP, and an \fCassociative container\fP (using equivalent keys)\&. For a \fCmultiset<Key>\fP the key_type and value_type are Key\&.
.PP
Multisets support bidirectional iterators\&.
.PP
The private tree data is declared exactly the same way for set and multiset; the distinction is made entirely in how the tree functions are called (*_unique versus *_equal, same as the standard)\&.
