pt.unl.fct.di.novasys.babel2.events.StartEvent
Record Components:
runtime - the Babel runtime that is starting
channel - the ComposedBabelChannel assigned to the receiving protocol
All Implemented Interfaces:
BabelEvent
public record StartEvent(Babel runtime, ComposedBabelChannel channel) extends Record implements BabelEvent
Special BabelEvent delivered exactly once to each protocol when the Babel runtime starts (i.e., when Babel.init() is called).

The event carries the Babel runtime instance and the BabelChannel assigned to the protocol, giving the protocol everything it needs during its BabelProtocol.init(Babel, ComposedBabelChannel) callback.
