Why Alarm both accepts and returns IMetric

[kornicameister]

Hello guys,

as in the title, I wonder what exactly is the purpose of an Alarm that accepts IMetric and returns IMetric?
You cannot import the metric, right? There's no API for that, so again - why would L2 Alarm operate on IMetric ?\

Cheers,

Not to mention that, at least in Python, it is perfectly fine to, for instance, call with(...) method that belongs to Metric and override some properties.
