Triggersedit
Every watch must have a trigger
that defines when the watch execution process
should start. When you create a watch, its trigger is registered with the
appropriate Trigger Engine. The trigger engine is responsible for evaluating
the trigger and triggering the watch when needed.
Watcher is designed to support different types of triggers, but only time-based
schedule
triggers are currently available.
