This is mostly only used for unittests, and even then unittests of metrics are rare. Is this a common use case for you?

In some cases I use metric values collected by Prometheus for internal calculations and statistics. It is very handy to directly use the existing instrumentation, otherwise I would have to duplicate the code.
I was wondering because the child-classes already had the getters but not the nolabel versions.

It seems to be useless. I will fix this. But I have no access to my development machine until Monday.

The import wasn't useless. It doesn't compile this way. But after qualifying the return value with Child.Value it works without import.

The build fails with the goal org.apache.maven.plugins:maven-javadoc-plugin:2.8:aggregate.
Do you have any idea what is going wrong here?

Offhand you're missing a </p>

Thanks for the response. The cause was the missing qualification of the return type.

Thanks!
