• Result.intoGroups(Field[], Class)
• Result.into(Class)

Method Detail

provide

<R extends Record,E> RecordMapper<R,E> provide(RecordType<R> recordType,
                                               Class<? extends E> type)

Provide a RecordMapper instance.

Implementations are free to choose whether this method returns new instances at every call or whether the same instance is returned repetitively.

A RecordMapper instance should be able to map any number of records with the same RecordType. For example, for Record.into(Class), provide() and RecordMapper.map(Record) are called only once. For Result.into(Class), provide() is called only once, but RecordMapper.map(Record) is called several times, once for every Record in the Result.

Parameters:

recordType - The RecordType of records that shall be mapped by the returned RecordMapper.

type - The user type that was passed into Record.into(Class) or any other method.

Returns:

A RecordMapper instance.
