&& BloombergLP::bslmf::IsTransparentPredicate<COMPARATOR,LOOKUP_KEY>::value;Return the address of a link whose key is equivalent to the specified key (according to this hash-table's comparator), and a null pointer value if no such link exists. If this hash-table contains more than one element having the supplied key, return the first such element (from the contiguous sequence of elements having the same key). The behavior is undefined unless key is equivalent to the elements of at most one equivalent-key group.
