Class SetupLocks

java.lang.Object

com.atlassian.confluence.setup.SetupLocks

public class SetupLocks
extends Object

Provide locks for actions so that they don't get run multiple times at once. Be aware that this class will be instantiated in the setup context, and in the application context, and that locks will not persist between contexts. If you wish to lock between contexts you'll need to use a different mechanism.
