Method Detail

create

VOData create()

Factory method to create an empty VODataDao entity with an already assigned identifier. The advantage of this approach, coupled with the fact that we're using the id for equals, is that equality test's are immediately possible and therefore independent from the persistence state of the entity. This in contrast to other solutions where auto generated Keys are used which must wait until the object is persisted or differentiate between transient and managed states.

Returns:

a new (non managed), empty VODataDao entity with an already assigned identifier.
