用actor model实现intel tbb这样的用法

关于什么事actor model，什么事intel tbb这样的用法我就不详细说了，具体请上网查文档

class MyActor

{

	F f;

	MyActor inputs[];

	MyActor outputs[];

	int n;

	#internal

	void run()

	{

		f();

		for o in outputs:

			sendMsg(o, this)

	}

	##1

	void addOutput(o)

	{

		outputs.append(o);

	}

	##2

	void onFirstRun()

	{

		if inputs.empoty()

			run()

	}

	##3

	void onMsg(id)

	{

		n++;

		if(n==inputs.size())

			run()

	}

}

def task(g, f, dependencies)

{

	a= MyActor(f, dependencies);

	// Tell dependencies add this actor to trigger list

	for depend in dependencies:

		depend.addOutput(a)

	return a

}

t1 = task([](){hello});

t2 = task([](){world}, t1);

g.run()
