:mrdocs:

This class implements the methods required by `bsl::ForwardIterator` to provide forward iterators. As such, an instance of this class represents a position within a flat hash table. This class uses no features of the `ENTRY` type except for addresses of `ENTRY` objects.

| Assign to this `FlatHashTable_IteratorImp` the value of the specified `rhs`.
| xref:BloombergLP/bdlc/FlatHashTable_IteratorImp/operator_star.adoc[`operator*`] 
| Return a reference to the element referred to by this `FlatHashTable_IteratorImp`. The behavior is undefined unless this `FlatHashTable_IteratorImp() != *this`.
| xref:BloombergLP/bdlc/FlatHashTable_IteratorImp/operator_inc.adoc[`operator++`] 
| Advance the `FlatHashTable_IteratorImp` to the next present element in the underlying flat hash table. If there is no such element, assign this object to `FlatHashTable_InteratorImp()`. The behavior is undefined unless this `FlatHashTable_IteratorImp` refers to a valid element of the underlying sequence.

| Return true if the specified `a` and `b` are equal. Two `FlatHashTable_IteratorImp` objects are equal if they both refer to the same element of the underlying flat hash table, or are both not dereferenceable. The behavior is undefined unless `a` and `b` refer to the same `FlatHashTable`.
