Class StdChannel

java.lang.Object
  tcl.lang.channel.Channel
      tcl.lang.channel.StdChannel

public class StdChannel
extends Channel

Subclass of the abstract class Channel. It implements all of the methods to perform read, write, open, close, etc on system stdio channels.

Field Summary

static int	STDERR Used to indicate that this channel is a standard error channel
static int	STDIN Used to indicate that this channel is a standard input channel
static int	STDOUT Used to indicate that this channel is a standard output channel

Method Detail

setIn

@Deprecated
public static void setIn(InputStream in)

Deprecated.

Reassign the standard input stream to a new stream. This will change the underlying stream for all interpreters. This use is deprecated; applications should unregister the stdin Channel and open a new Channel to replace stdin.

Parameters:

in - InputStream to replace standard input with

setOut

@Deprecated
public static void setOut(PrintStream out)

Deprecated.

Reassign the standard output stream to a new stream. This will change the underlying stream for all interpreters. This use is deprecated; applications should unregister the stdout Channel and open a new Channel to replace it.

Parameters:

out - OutputStream to replace standard input with

setErr

@Deprecated
public static void setErr(PrintStream err)

Deprecated.

Reassign the standard error stream to a new stream. This will change the underlying stream for all interpreters. This use is deprecated; applications should unregister the stderr Channel and open a new Channel to replace it.

Parameters:

err - OutputStream to replace standard input with

getInputStream

protected InputStream getInputStream()
                              throws IOException

Description copied from class: Channel

This method should be overridden in the subclass to provide a channel specific InputStream object.

Specified by:

getInputStream in class Channel

Throws:

IOException

getOutputStream

protected OutputStream getOutputStream()
                                throws IOException

Description copied from class: Channel

This method should be overridden in the subclass to provide a channel specific OutputStream object.

Specified by:

getOutputStream in class Channel

Throws:

IOException
