BloombergLP::bdlcc::StripedUnorderedMultiMap::ReadOnlyVisitorFunction

An alias to a function meeting the following contract: ` /// Visit the specified value attribute associated with the /// specified key. Return true if this function may be /// called on additional elements, and false otherwise (i.e., /// if no other elements should be visited). Note that this /// functor can not change the values associated with key /// and value. bool readOnlyVisitorFunction(const VALUE& value, const KEY& key); `
