Ledge Components
Provides a common facility for associating event generators with receivers.
This component was created to remove the burden of managing listener lists from objects that generate events.
'Events' that are dealt with here are experssed with method calls on
concrete objects. Propagating these events to other JVMs will usually
require some additional effort, like java.rmi.Remote
listeners, or listeners generating messages and propagating them to other
JVMs using i.e. Notification, with notification listeners
parsing messages, and firing events on the other local EventSystem.
The 'EventSystem' implements 'EventForwarder' interface, thus this component acts as the ledge instance wide event forwarder. If need arsises, you can create additional private event forwarders separate from the global one. See also 'InboundEventForwarder' and 'OutboundEventForwarder'.
