Traditionally, we can use switch/case for only comparing a single sequence with a string value. And it has to be a proper match, meaning, there is no way to use a like or contains statement in the match. Internal override bool trygetmap(string identity, dataspace typespace, bool ignorecase, out map map) {. The idea behind the identity map pattern is that every time we read a record from the database, we first check the a secondary benefit to the identity map is that, since it acts as a cache, it reduces the number of database calls needed to retrieve objects, which yields a performance enhancement.
