Create an unordered multiset having the same value as the specified original object that uses the specified basicAllocator to supply memory. Use a copy of original.hash_function() to generate hash values for the keys contained in this unordered multiset. Use a copy of original.key_eq() to verify that two keys are equivalent. This method requires that the (template parameter) type KEY be copy-insertable into this unordered multiset (see {Requirements on KEY}). Note that a bslma::Allocator * can be supplied for basicAllocator if the (template parameter) type ALLOCATOR is bsl::allocator (the default).
