bsl::unordered_multiset::unordered_multiset

Create an unordered multiset and insert each value_type object in the specified values initializer list. Optionally specify an initialNumBuckets indicating the initial size of the array of buckets of this container. If initialNumBuckets is not supplied, a single bucket is used. Optionally specify a hashFunction used to generate the hash values for the keys contained in this unordered multiset. If hashFunction is not supplied, a default‐constructed object of the (template parameter) type HASH is used. Optionally specify a key‐equality functor keyEqual used to verify that two keys are equivalent. If keyEqual is not supplied, a default‐constructed object of the (template parameter) type EQUAL is used. Optionally specify a basicAllocator used to supply memory. If basicAllocator is not supplied, a default‐constructed object of the (template parameter) type ALLOCATOR is used. If the type ALLOCATOR is bsl::allocator and basicAllocator is not supplied, the currently installed default allocator is used to supply memory. 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 type ALLOCATOR is bsl::allocator (the default).
