Package org.hibernate.type.descriptor.converter.spi

Interface BasicValueConverter<D,R>

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.
