Declared in <bdlc_flathashmap.h>
Return a pair of iterators defining the sequence of modifiable elements in this map having the specified key, where the first iterator is positioned at the start of the sequence and the second iterator is positioned one past the end of the sequence. If this map contains no elements having a key equivalent to key, then the two returned iterators will have the same value. Note that since a map maintains unique keys, the range will contain at most one element.
Return a pair of const_iterator`s defining the sequence of elements in this map having the specified `key, where the first iterator is positioned at the start of the sequence and the second iterator is positioned one past the end of the sequence. If this map contains no elements having a key equivalent to key, then the two returned iterators will have the same value. Note that since a map maintains unique keys, the range will contain at most one element.

&& BloombergLP::bslmf::IsTransparentPredicate<EQUAL,LOOKUP_KEY>::value;Return a pair of iterators providing non‐modifiable access to the sequence of value_type objects in this unordered map that are equivalent to the specified key, where the first iterator is positioned at the start of the sequence and the second iterator is positioned one past the end of the sequence. If this unordered map contains no value_type objects equivalent to key, then the two returned iterators will have the same value. Note that since an unordered map maintains unique keys, the range will contain at most one element.
