Component

Your components can receive Events that are being spawned by the System. It's up to your component to handle these.

type alias ComponentEventHandlers componentMsgIn =
{ onPIDNotFound : PID -> EventHandler componentMsgIn
, onKill : EventHandler componentMsgIn
}

Components need to supply the following event handlers

systemDefault : ComponentEventHandlers componentMsgIn

You can choose to apply a sytem default behaviour

It might be easy to start with systemDefault when specifying your components event handlers.

{ systemDefault | onKill = beforeDefault SaveProgress }
ignoreAll : ComponentEventHandlers componentMsgIn

You can choose to ignore all events
