Examples with CascadeStyle org.hibernate.engine.CascadeStyle used on opensource projects

Example 1 with CascadeStyle

use of org.hibernate.engine.CascadeStyle in project Gemma by PavlidisLab.

the class AuditAdvice method processAssociations.

/**
 * Fills in audit trails on newly created child objects after a 'create' or 'update'. It does not add 'update'
 * events on the child objects.
 * Thus if the update is on an expression experiment that has a new Characteristic, the Characteristic will have a
 * 'create' event, and the EEE will get an added update event (via the addUpdateAuditEvent call elsewhere, not here)
 *
 * @see AclAdvice for similar code for ACLs
