BloombergLP::bdlc::FlatHashSet::FlatHashSet

Create a FlatHashSet object initialized by insertion of the values from the input iterator range specified by first through last (including first, excluding last). Optionally specify a capacity indicating the minimum initial size of the underlying array of entries of this container. If capacity is not supplied or is 0, no memory is allocated. Optionally specify a hash functor used to generate hash values associated with the elements in this container. If hash is not supplied, a default‐constructed object of the (template parameter) type HASH is used. Optionally specify an equality functor equal used to verify that two elements are equivalent. If equal 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 or is 0, the currently installed default allocator is used. The behavior is undefined unless first and last refer to a sequence of valid values where first is at a position at or before last. Note that if a member of the input sequence is equivalent to an earlier member, the later member will not be inserted.
