EclipseLink Core 4.0.2 · org.eclipse.persistence.annotations.Convert

The Convert annotation specifies that a named converter should be used with the corresponding mapped attribute. The Convert annotation has the following reserved names:

serialized: Will use a SerializedObjectConverter on the associated mapping. When using a SerializedObjectConverter the database representation is a binary field holding a serialized version of the object and the object-model representation is a the actual object.
class-instance: Will use an ClassInstanceConverter on the associated mapping. When using a ClassInstanceConverter the database representation is a String representing the Class name and the object-model representation is an instance of that class built with a no-args constructor.
xml: Will use an SerializedObjectConverter with the XMLSerializer on the associated mapping. When using a XMLSerializer the database representation is a character field holding a serialized version of the object and the object-model representation is a the actual object.
json: Will use an SerializedObjectConverter with the JSONSerializer on the associated mapping. When using a JSONSerializer the database representation is a character field holding a serialized version of the object and the object-model representation is a the actual object.
kryo: Will use an SerializedObjectConverter with the KryoSerializer on the associated mapping. When using a KryoSerializer the database representation is a binary field holding a serialized version of the object and the object-model representation is a the actual object.
none - Will place no converter on the associated mapping. This can be used to override a situation where either another converter is defaulted or another converter is set.

When these reserved converters are not used, it is necessary to define a converter to use using the @Converter annotation.

NONE	back to summary
public static final String NONE Constant name for no converter.

SERIALIZED	back to summary
public static final String SERIALIZED Constant name for the reserved Java serialization converter. This will serialize the

XML	back to summary
