BloombergLP::bdlc::FlatHashMap::operator=

Assign to this object the value resulting from first clearing this map and then inserting each object in the specified values initializer list, ignoring those objects having a value whose key is equivalent to that which appears earlier in the list; return a reference providing modifiable access to this object. This method requires that the (template parameter) type KEY be copy‐insertable into this map (see {Requirements on KEY, HASH, and EQUAL}).
