org.hibernate.type.descriptor.converter.AttributeConverterSqlTypeDescriptorAdapter
Adapter for incorporating JPA {@link AttributeConverter} handling into the SqlTypeDescriptor contract.
Essentially this is responsible for mapping to/from the intermediate database type representation. Continuing the {@code AttributeConverter} example from{@link org.hibernate.mapping.SimpleValue#buildAttributeConverterTypeAdapter()}, the "intermediate database type representation" would be the String representation. So on binding, we convert the incoming Integer to String; on extraction we extract the value as String and convert to Integer. @author Steve Ebersole

    // find the JavaTypeDescriptor representing the "intermediate database type representation".  Back to the
    //     illustration, this should be the type descriptor for Strings
    final JavaTypeDescriptor intermediateJavaTypeDescriptor = JavaTypeDescriptorRegistry.INSTANCE.getDescriptor( databaseColumnJavaType );
    // and finally construct the adapter, which injects the AttributeConverter calls into the binding/extraction
    //     process...
    final SqlTypeDescriptor sqlTypeDescriptorAdapter = new AttributeConverterSqlTypeDescriptorAdapter(
        attributeConverterDefinition.getAttributeConverter(),
        sqlTypeDescriptor,
        intermediateJavaTypeDescriptor
    );
