    public interface IUpdatable
    Bolt or spout instances should implement this method if they wish to be informed of changed to the topology context during the lifecycle of the instance. The TopologyContext is backed by elements of the physical plan, which can change during a scaling event. Instances that need to adapt to such changes should implement this interface to receive a callback when a change occurs.
