Concurrency library for Ceylon

Concurrency for Ceylon

There hasn't been good ways to do concurrent operations for Ceylon. However, using this library may help doing concurrent operations easier.

Executing concurrent code via Dispatch:

  Dispatch.run(() => print("Hello world!"));

Executing concurrent code via Client and Servers:

class Exec() satisfies Client {
	shared void exec() {
		MyServer s = MyServer();
		s.sendMessage("hi to server", 12345, this);
	}
	
	shared actual void receiveObject(Object obj, Integer msgId, Server sender) {
		// not implemented
	}
	
	shared actual void receiveTextMessage(String msg, Integer msgId, Server sender) {
		print(msg);
	}
	
}

class MyServer() extends Server() {
	
	shared actual void reactToMessage(String msg, Integer msgId) {
		this.sendMessageToSender("hi from server", 12345);
	}
	
	shared actual void reactToObject(Object obj, Integer msgIdr) {
		// not implemented
	}
	
}
