Annotation Type SerializedObject
SerializedObject annotation is used to set an
org.eclipse.persistence.descriptors.SerializedObjectPolicy on an Entity or MappedSuperClass.
If SerializedObjectPolicy is specified Eclipselink writes out the whole entity object with its
privately owned (and nested privately owned) entities and element collections into an additional
(likely BLOB) field in the database. That field could be specified in the annotation, it defaults to "SOP" in the main table.
Examples:
@Entity
@SerializedObject(MySerializedObjectPolicy.class);
public class Employee {...
@Entity
@SerializedObject(value = MySerializedObjectPolicy.class, column = @Column(name="SERIALIZED"));
public class Address {...
If SerializedObjectPolicy is set on an entity then SerializedObjectPolicies with the same field are set
on all inheriting entities.
The query that uses SerializedObjectPolicy extracts the whole object from that field.
To read object(s) using SerializedObjectPolicy the query should specify- Since:
