jOOQ 3.18.7 · org.jooq.RecordMapperProvider

A provider for RecordMapper instances.

In order to inject custom Record to POJO mapping behaviour, users can supply a custom RecordMapperProvider to their Configuration instances. This provider will be used in any of these methods (non-exhaustive list):

`Cursor`

`Record`

Record#into(Class)

`Result`

`ResultQuery`

`DAO`

Most DAO methods make use of any of the above methods

While not strictly required, it is advisable to implement a RecordMapperProvider whose behaviour is consistent with the configured RecordUnmapperProvider.

public <R extends Record, E> @NotNull 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:RecordType<R> The `RecordType` of records that shall be mapped by the returned `RecordMapper`. type:Class<? extends E> The user type that was passed into `Record#into(Class)` or any other method.
