brooklyn.policy.loadbalancing
[Java] Class ItemsInContainersGroupImpl

java.lang.Object
  brooklyn.entity.basic.AbstractEntity
      brooklyn.entity.basic.AbstractGroupImpl
          brooklyn.entity.basic.DynamicGroupImpl
              brooklyn.policy.loadbalancing.ItemsInContainersGroupImpl
All Implemented Interfaces:
ItemsInContainersGroup
public class ItemsInContainersGroupImpl
extends DynamicGroupImpl

A group of items that are contained within a given (dynamically changing) set of containers. The setContainers(brooklyn.entity.Group) sets the group of containers. The membership of that group is dynamically tracked. When containers are added/removed, or when an items is added/removed, or when an Moveable item is moved then the membership of this group of items is automatically updated accordingly. For example: in Monterey, this could be used to track the actors that are within a given cluster of venues.
