Handling events

public override function clone():Event
{
return new AlarmEvent(message);

/**

The overridden clone() method needs to return a new instance of the custom Event subclass, with all the custom
properties set to match the current instance. In the overridden toString() method, the utility method
formatToString() (inherited from Event) is used to provide a string with the name of the custom type, as well as the
names and values of all its properties.
