Examples of com.espertech.esper.client.EventPropertyGetter

com.espertech.esper.client.EventPropertyGetter
Get property values from an event instance for a given event property. Instances that implement this interface are usually bound to a particular {@link com.espertech.esper.client.EventType} and cannotbe used to access {@link EventBean} instances of a different type.
