Class GroupsUpdate

java.lang.Object

com.google.gerrit.server.group.GroupsUpdate

public class GroupsUpdate
extends Object

A database accessor for write calls related to groups.

All calls which write group related details to the database (either ReviewDb or NoteDb) are gathered here. Other classes should always use this class instead of accessing the database directly. There are a few exceptions though: schema classes, wrapper classes, and classes executed during init. The latter ones should use GroupsOnInit instead.

If not explicitly stated, all methods of this class refer to internal groups.
