Persistence

The Persistence annotation indicates the persistence state of an entity class's field. It has a single attribute, value, which represents the persistence mode of the field: transient or persistent. By default, a field is persistent, meaning the annotation can be omitted. Its purpose is to support greater model flexibility, allowing for specific class fields to not be persisted.

Persistence Example

The below example shows how a field can be marked transient such that it will not be persisted.

public class Foo {

    @Persistence(PersistenceMode.Transient)
    private int mBar; // this field will NOT be persisted

    private int mBaz; // this field WILL be persisted

}
