zeromq/jzmq push/pull模式及java代码

引用图片：http://iyuan.iteye.com/blog/974040

模型描述： 
1.上游(任务发布) 
2.工人(中间，具体工作) 
3.下游(信号采集或者工作结果收集) 

上代码：

push：

package com.zeromq.test.push_pull;
import org.zeromq.ZMQ;
/**
 * @author larry
 * @email [email protected]
 * @version 2012-6-5 上午11:30:46
 */
public class push_demo {
	public static void main(String[] args) {
		ZMQ.Context context = ZMQ.context(1);
		ZMQ.Socket sync = context.socket(ZMQ.PUSH);
		sync.connect("tcp://localhost:5564");
		sync.send("".getBytes(), 0);
		int update_nbr;
		for (update_nbr = 0; update_nbr < 10; update_nbr++) {
			sync.send("Rhubarb".getBytes(), ZMQ.NOBLOCK);
		}
		sync.send("END".getBytes(), 0);
	}
}

pull：

/**
 * 
 */
package com.zeromq.test.push_pull;
import org.zeromq.ZMQ;
/**
 * @author larry
 * @email [email protected]
 * @version 2012-6-5 上午11:37:46
 */
public class pull_demo {
	public static void main(String[] args) {
		ZMQ.Context context = ZMQ.context(1);
		ZMQ.Socket sync = context.socket(ZMQ.PULL);
		sync.bind("tcp://*:5564");
		sync.recv(0);
		int update_nbr = 0;
		while (true) {
			byte[] stringValue = sync.recv(0);
			String string = new String(stringValue);
			if (string.equals("END")) {
				break;
			}
			update_nbr++;
			System.out.println("Received " + update_nbr + " updates. :" + string);
		}
		sync.close();
		context.term();
	}
