Having an abstract
build()
method allows writing generic code for the different builders.For context, I'm currently updating a library from
simpleclient
to the new 1.X version. The library converts metrics from Apache Kafka where we can have multiple metric objects with the same metric name but different labels.With
simpleclient
, we could also have multipleMetricFamilySamples
with the same name, but that's not the case anymore withMetricSnapshots
where eachMetricSnapshot
must have a unique name.So when converting metrics from Kafka, we need to keep un-built
MetricSnapshot.Builder
and add datapoints when we find metrics with the same names. In this example being able to store variousMetricSnapshot.Builder
objects in a collection is useful and allows building them all easily.
