Examples of com.sun.sgs.app.DataManager.createReference()

com.sun.sgs.app.DataManager.createReference()
Creates a managed reference to an object, storing the object in the data manager if it is transient. Applications should use managed references when a managed object refers to another managed object, either directly or indirectly through non-managed objects. @param < T> the type of the object @param object the object @return the managed reference @throws IllegalArgumentException if object does notimplement both {@link ManagedObject} and {@link Serializable} @throws ObjectNotFoundException if the object has been removed @throws TransactionException if the operation failed because of aproblem with the current transaction
