brooklyn.entity.proxy
[Java] Class LoadBalancerCluster

java.lang.Object
  groovy.lang.GroovyObjectSupport
      brooklyn.entity.basic.AbstractEntity
          brooklyn.entity.basic.AbstractGroup
              brooklyn.entity.group.DynamicCluster
                  brooklyn.entity.proxy.LoadBalancerCluster
All Implemented Interfaces:
LoadBalancer
public class LoadBalancerCluster
extends DynamicCluster

A cluster of load balancers, where configuring the cluster (through the LoadBalancer interface) will configure all load balancers in the cluster. Config keys (such as LoadBalancer.serverPool and LoadBalancer.urlMappings) are automatically inherited by the children of the load balancer cluster. It is through that mechanism that configuration changes on the cluster will be applied to all child load balancers (i.e. by them all sharing the same serverPool and urlMappings etc).
