Class LastModificationDateManagement

java.lang.Object

com.communote.server.core.lastmodifieddate.LastModificationDateManagement

@Service
 @Transactional
public class LastModificationDateManagement
extends Object

Service to retrieve the crawl-last-modification dates of certain entities.

The crawl-last-modification dates are similar to the last-modification dates of the entities but usually are also updated by other operations. For example the last-modification date of a topic is updated when the title, alias, description, the create system notes flag and/or the tag assignment is modified. The crawl-last-modification date of the topic is also updated if the topic access rights are changed.
