NIO的管道(Pipe)是一种打通两个线程之间数据传输的一种方式。Pipe包含两个channel:
1)Source Channel
2)Sink Channel
你可以向SinkChannel写入数据,然后从SourceChannel读取出来。如图
创建一个Pipe
Pipe pipe = Pipe.open();
写入数据到Pipe
Pipe.SinkChannel sinkChannel = pipe.sink();
String newData = "New String to write to file..." + System.currentTimeMillis(); ByteBuffer buf = ByteBuffer.allocate(48); buf.clear(); buf.put(newData.getBytes()); buf.flip(); while(buf.hasRemaining()) { sinkChannel.write(buf); }
从Pipe读取数据
Pipe.SourceChannel sourceChannel = pipe.source();
ByteBuffer buf = ByteBuffer.allocate(48); int bytesRead = inChannel.read(buf);
