Examples of org.apache.s4.base.Event

org.apache.s4.comm.topology.ZkClient
The base event class in S4. The base class supports generic key/value pairs which us useful for rapid prototyping and for inter-application communication. For greater efficiency and type safety, extend this class to create custom event types.
