Interface ConverterProvider

All Known Implementing Classes:
DefaultConverterProvider
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 ConverterProvider
A ConverterProvider provides Converter implementations for any combination of types <T> and <U>.

ConverterProvider can be used together with RecordMapper, e.g. when mapping JSON or XML data types onto POJO types using third party libraries like Jackson, Gson, JAXB, or others.

The general expectation is for a ConverterProvider to be side-effect free. Two calls to provide(Class, Class) should always produce the same Converter logic and thus conversion behaviour, irrespective of context, other than the Configuration that hosts the Configuration.converterProvider(). This effectively means that it is possible for jOOQ to cache the outcome of a provide(Class, Class) call within the context of a Configuration or any derived context, such as an ExecuteContext, to greatly improve performance.
