Create an empty set. Optionally specify a `comparator` used to order keys contained in this object. If `comparator` is not supplied, a default‐constructed object of the (template parameter) type `COMPARATOR` 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. Note that a `bslma::Allocator *` can be supplied for `basicAllocator` if the type `ALLOCATOR` is `bsl::allocator` (the default).
