Examples of com.sun.sgs.app.ManagedObject

com.sun.sgs.app.ManagedObject
A marker interface implemented by shared, persistent objects managed by {@link DataManager}. Classes that implement {@code ManagedObject} must alsoimplement {@link Serializable}, as should any non-managed objects they refer to. Any instances of {@code ManagedObject} that a managed object refers todirectly, or indirectly through non-managed objects, need to be referred to through instances of {@link ManagedReference}.
Classes that implement {@code ManagedObject} should not provide {@code writeReplace} or {@code readRestore} methods to designate replacementobjects during serialization. Object replacement would interfere with the object identity maintained by the {@code DataManager}, and is not permitted.
Classes that implement {@code ManagedObject} can provide {@code readObject}and {@code writeObject} methods to customize their serialization behavior,but the {@code writeObject} methods should not perform calls to methods thatrequire a current transaction. @see DataManager @see ManagedReference @see Serializable
