* methods (non-exhaustive list):
*
Cursor
*
* - {@link Cursor#fetchInto(Class)}
* - {@link Cursor#fetchOneInto(Class)}
*
* Record
*
* - {@link Record#into(Class)}
*
* Result
*
* - {@link Result#intoMap(Field, Class)}
* - {@link Result#intoMap(Field[], Class)}
* - {@link Result#intoGroups(Field, Class)}
* - {@link Result#intoGroups(Field[], Class)}
* - {@link Result#into(Class)}
*
* ResultQuery
*
* - {@link ResultQuery#fetchMap(Field, Class)}
* - {@link ResultQuery#fetchMap(Field[], Class)}
* - {@link ResultQuery#fetchGroups(Field, Class)}
* - {@link ResultQuery#fetchGroups(Field[], Class)}
* - {@link ResultQuery#fetchInto(Class)}
* - {@link ResultQuery#fetchOneInto(Class)}
*
* DAO
*
* - Most {@link DAO} methods make use of any of the above methods
