The ServerEventSource component defines an interface for components that can serve as the source for external events. These components provide events for Global Automatic Listener activities.
When building an external event listening component in Java, the component must implement the fuego.components.ServerEventSource interface. By implementing ServerEventSource, the class file appears in the Listener class drop-down menu on the activity properties dialog box. The listener Java class exposes the possible types for the event data by defining at least one public attribute named with the ARG_ prefix. The argument types should be catalogued before cataloging the listener component.
