[Java] Class DefaultBalanceablePoolModel

java.lang.Object
  brooklyn.policy.loadbalancing.DefaultBalanceablePoolModel
All Implemented Interfaces:
BalanceablePoolModel
public class DefaultBalanceablePoolModel

Standard implementation of BalanceablePoolModel, providing essential arithmetic for item and container workrates and thresholds. See subclasses for specific requirements for migrating items.
