[Java] Class HttpLatencyDetector

java.lang.Object
  brooklyn.policy.basic.AbstractEntityAdjunct
      brooklyn.enricher.basic.AbstractEnricher
          brooklyn.enricher.HttpLatencyDetector

public class HttpLatencyDetector
extends AbstractEnricher

An Enricher which computes latency in accessing a URL. See comments on the methods in the static builder() this exposes.

This is currently tested against relatively simple GET requests, optionally returned from sensors. It does not currently support POST and has limited support for https.
