performDetachedEntityDeletionCheck

protected void performDetachedEntityDeletionCheck(DeleteEvent event)

Description copied from class: DefaultDeleteEventListener

Called when we have recognized an attempt to delete a detached entity.

Overrides:

performDetachedEntityDeletionCheck in class DefaultDeleteEventListener

Parameters:

event - The event.
