What is it all about?
Signals are light-weight, strongly-typed AS3 messaging tools. Write your application with better APIs and less boilerplate than AS3 Events.
• A Signal is essentially a mini-dispatcher specific to one event, with its own array of listeners. • A Signal gives an event a concrete membership in a class. • Listeners subscribe to real objects, not to string-based channels. • Event string constants are no longer needed. • Signals are inspired by C# events and signals/slots in Qt.
