[Java] Class AbstractAggregatingEnricher

java.lang.Object
  brooklyn.policy.basic.AbstractEntityAdjunct
      brooklyn.enricher.basic.AbstractEnricher
          brooklyn.enricher.basic.AbstractAggregatingEnricher
All Implemented Interfaces:
SensorEventListener
public abstract class AbstractAggregatingEnricher
extends AbstractEnricher

AggregatingEnrichers implicitly subscribes to the same sensor on all entities inside an Group and should emit an aggregate on the target sensor

Field Summary
protected S defaultValue

protected AttributeSensor target

protected java.util.Map values

Users of values should either on it synchronize when iterating over its entries or use copyOfValues to obtain an immutable copy of the map.
