Configuring a Serialized Object Mapping

Use a serialized object mapping to specify that a persistent property should be persisted as a serialized stream of bytes.

You define a serialized object at one of the property (getter or setter method) or field level of your entity.

For more information, see the following:

• "Understanding Direct-to-Field Mapping" in the Oracle TopLink Developer's Guide

• "Using a Converter Mapping" in the Oracle TopLink Developer's Guide

• "Serialized Object Converter" in the Oracle TopLink Developer's Guide

Using Annotations

Example 7-19 shows how to use the @Serialized annotation to specify a serialized object mapping for field picture.

Example 7-19 @Serialized

@Serialized(fetch=EAGER)
@Column(name="PICTURE")
public Byte[] getPicture() {
    return picture;
}
