Class JarStreamMetricSource

java.lang.Object
  cyvis.core.metrics.sources.MetricSource
      cyvis.core.metrics.sources.JarStreamMetricSource

public class JarStreamMetricSource
extends MetricSource

Supports collecting metrics from a .jar file for which we only have an input stream (but not a File on disk). In this case we can't give very sensible progress notifications, but we try anyway.

JarFileMetricSource is used if we have a file on disk, because it gives accurate progress notifications.
