brooklyn.policy.autoscaling
[Java] Class AutoScalerPolicy

java.lang.Object
  brooklyn.policy.basic.AbstractEntityAdjunct
      brooklyn.policy.basic.AbstractPolicy
          brooklyn.policy.autoscaling.AutoScalerPolicy

@SuppressWarnings({"rawtypes", "unchecked"})
public class AutoScalerPolicy
extends AbstractPolicy

Policy that is attached to a Resizable entity and dynamically adjusts its size in response to emitted POOL_COLD and POOL_HOT events. (This policy does not itself determine whether the pool is hot or cold, but instead relies on these events being emitted by the monitored entity itself, or by another policy that is attached to it; see, for example, LoadBalancingPolicy.)
