All Implemented Interfaces:

bucket.core.persistence.ObjectDao, AttachmentDataDao, TransactionalAttachmentDataDao, org.springframework.beans.factory.InitializingBean

public class HibernateAttachmentDataDao
extends com.atlassian.hibernate.HibernateObjectDao
implements TransactionalAttachmentDataDao

This class defines an AttachmentDataDao that stores Attachment data in a Hibernate-managed database.

As a result, it is transactional (can be rolled back), so it implements the TransactionalAttachmentDataDao interface.
