/**
 * The {@code CriteriaUpdate} interface defines functionality for
 * performing bulk update operations using the Criteria API.
 *
 * 

Criteria API bulk update operations map directly to database * update operations, bypassing any optimistic locking checks. * Portable applications using bulk update operations must manually * update the value of the version column, if desired, and/or manually * validate the value of the version column. The persistence context * is not automatically synchronized with the result of the bulk update. * *
