Why doesn't more Java code use PipedInputStream / PipedOutputStream?

Question

I\'ve discovered this idiom recently, and I am wondering if there is something I am missing. I\'ve never seen it used. Nearly all Java code I\'ve worked with in the wild fav

Answer 1

I too only discovered the PipedInputStream/PipedOutputStream classes recently.

I am developing an Eclipse plug-in that needs to execute commands on a remote server via SSH. I am using JSch and the Channel API reads from an input stream and writes to an output stream. But I need to feed commands through the input stream and read the responses from an output stream. Thats where PipedInput/OutputStream comes in.

import java.io.PipedInputStream;
import java.io.PipedOutputStream;

import com.jcraft.jsch.Channel;

Channel channel;
PipedInputStream channelInputStream = new PipedInputStream();
PipedOutputStream channelOutputStream = new PipedOutputStream();

channel.setInputStream(new PipedInputStream(this.channelOutputStream));
channel.setOutputStream(new PipedOutputStream(this.channelInputStream));
channel.connect();

// Write to channelInputStream
// Read from channelInputStream

channel.disconnect();
