BloombergLP::bslalg::HashTableImpUtil::findTransparent

Return the address of the first link in the list element of the specified anchor having a value matching (according to the specified transparent equalityFunctor) the specified key in the bucket that holds elements with the specified hashCode if such a link exists, and return 0 otherwise. The behavior is undefined unless, for the provided KEY_CONFIG and some hash function, HASHER, anchor is well-formed (see isWellFormed) and HASHER(key) returns hashCode. KEY_CONFIG shall be a namespace providing the type names KeyType and ValueType, as well as a function that can be called as if it had the following signature: ` const KeyType& extractKey(const ValueType& obj); ` KEY_EQUAL shall be a functor that can be called as if it had the following signature: ` bool operator()(const LOOKUP_KEY& key1, const KEY_CONFIG::KeyType& key2)
