管道(Pipe)
Java的NIO管道是2个线程之间的单向数据连接,Pipe有一个source通道和一个sink通道,数据会被写到sink通道,从source通道读取
package com.nio;
import org.junit.Test;
import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.channels.Pipe;
public class TestPipe {
@Test
public void test1() throws IOException{
//1. 获取管道
Pipe pipe = Pipe.open();
//2. 将缓冲区中的数据写入到管道
ByteBuffer buf = ByteBuffer.allocate(1024);
Pipe.SinkChannel sinkChannel = pipe.sink();
buf.put("通过单向管道发送数据".getBytes());
buf.flip();
sinkChannel.write(buf);
//3. 读取缓冲区中的数据
Pipe.SourceChannel sourceChannel = pipe.source();
buf.flip();
int len = sourceChannel.read(buf);
System.out.println(new String(buf.array(),0,len));
sourceChannel.close();
sinkChannel.close();
}
}
