A RecordMapper is a mapper that can receive Record objects, when fetching data from the database, transforming them into a custom type <E>.

RecordMapper is used behind the scenes in methods like ResultQuery.fetchInto(Class), Result.into(Class), Record.into(Class<? extends Object>) and other methods called into(Class),
where the argument class is a Class of type E.

The default RecordMapper behaviour in the context of a Configuration can be overridden through that configuration's Configuration.recordMapperProvider() SPI. 
 The inverse operation is modelled by RecordUnmapper.
