BasicValueConverter (Hibernate Javadocs)

Type Parameters:

D - The Java type we use to represent the domain (object) type

R - The Java type we use to represent the relational type

All Known Subinterfaces:

JpaAttributeConverter<O,R>, StandardBooleanConverter<R>, StandardConverter<O,R>

All Known Implementing Classes:

ArrayConverter, CharBooleanConverter, CollectionConverter, DefaultDiscriminatorConverter, DiscriminatorConverter, EmbeddableDiscriminatorConverter, JpaAttributeConverterImpl, MappedDiscriminatorConverter, NumericBooleanConverter, TrueFalseConverter, YesNoConverter
```
@Incubating
public interface BasicValueConverter<D,R>
```
Support for basic-typed value conversions.
Conversions might be determined by:
- a custom JPA AttributeConverter, or
- implicitly, based on the Java type, for example, for Java enums.
