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
|
|
<<trigger-schedule,`schedule`>> triggers are currently available.
