Interface RecordMapper<R extends Record,E>

All Known Implementing Classes:

DefaultRecordMapper

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface RecordMapper<R extends Record,E>

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) 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.
