类 AttributeConverterSqlTypeDescriptorAdapter

java.lang.Object

org.hibernate.type.descriptor.converter.AttributeConverterSqlTypeDescriptorAdapter

所有已实现的接口:

Serializable, SqlTypeDescriptor

public class AttributeConverterSqlTypeDescriptorAdapter
extends Object
implements SqlTypeDescriptor

Adapter for incorporating JPA AttributeConverter handling into the SqlTypeDescriptor contract.

Essentially this is responsible for mapping to/from the intermediate database type representation. Continuing the AttributeConverter<Integer,String> example from 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.
