[Java] Class TimeFractionDeltaEnricher

java.lang.Object
  brooklyn.policy.basic.AbstractEntityAdjunct
      brooklyn.enricher.basic.AbstractEnricher
          brooklyn.enricher.basic.AbstractTypeTransformingEnricher
              brooklyn.enricher.TimeFractionDeltaEnricher

public class TimeFractionDeltaEnricher
extends AbstractTypeTransformingEnricher

Converts an absolute measure of time into a fraction of time, based on the delta between consecutive values and the elapsed time between those values. For example, if the values are for ProcessCpuTime (i.e. microseconds of CPU time for the given process), then this would convert it into a fraction (i.e. 100th of the percentage): (newVal-prevVal)/(newTimestamp/prevTimestamp). It also configured with the time units for the values.
