insertUnique(
KEY const& key,
bslmf::MovableRef<VALUE> value);If key already exists in this hash map, the value attribute of that element is set to value. Return 1 if an element is inserted, and 0 if an existing element is updated. The value object is left in a valid but unspecified state. If value is allocator-enabled and allocator() != value.allocator() this operation may cost as much as a copy. Note that the return value equals the number of elements inserted.
1 if an element is inserted, and 0 if an existing element is updated
