Class Collector

java.lang.Object

de.iip_ecosphere.platform.support.collector.Collector

public class Collector
extends Object

Simple data collector for test performance/regression. Build IDs are taken from the environment/system property "iip.ciBuildId". Setup is read from "oktoflow-collector.yml" in the user's home directory. Implements a simple data migration function to allow for adding additional fields. Initial quick and dirty solution, may be replaced, e.g., by Kieker.
