Event objects may support rules. These event objects don’t call a callback function when events happen but test whether any registered rule has at least one fulfilled condition and execute the actions associated with this rule. Event objects supporting the declarative API have three relevant methods: events.Event.addRules, events.Event.removeRules, and events.Event.getRules.<\/p>\n
