Constructor Details

PTY

public PTY()
    throws IOException

Create PTY for use with Eclipse console. Identical to PTY(Mode.CONSOLE).

Throws:

IOException

PTY

public PTY(PTY.Mode mode)
    throws IOException

Create PTY for given mode.

The provided mode indicates whether the pseudo terminal is used with the interactive Eclipse console or a terminal emulation:

• CONSOLE - the terminal is configured with no echo and stderr is redirected to a pipe instead of the PTY. This mode is not supported on windows
• TERMINAL - the terminal is configured with echo and stderr is connected to the PTY. This mode is best suited for use with a proper terminal emulation. Note that this mode might not be supported on all platforms. Known platforms which support this mode are: linux-x86, linux-x86_64, solaris-sparc, macosx.

Parameters:

mode - the desired mode of operation

Throws:

IOException - if the PTY could not be created

Since:

5.6

Method Details

isSupported

@Deprecated
public static boolean isSupported()

Deprecated.

Returns:

whether PTY support for console mode is available on this platform

isSupported

public static boolean isSupported(PTY.Mode mode)

Returns:

whether PTY support for given mode is available on this platform

Since:

5.6

validateSlaveName

public void validateSlaveName()
                       throws IOException

Test whether the slave name can be used as a tty device by external processes (e.g. gdb). If the slave name is not valid an IOException is thrown.

Throws:

IOException - if the slave name is not valid

Since:

5.6

getSlaveName

public String getSlaveName()

getMasterFD

public PTY.MasterFD getMasterFD()

isConsole

public final boolean isConsole()

Returns:

whether this pseudo terminal is for use with the Eclipse console.

Since:

5.2

getOutputStream

public PTYOutputStream getOutputStream()

getInputStream

public PTYInputStream getInputStream()

setTerminalSize

public final void setTerminalSize(int width,
 int height)

Change terminal window size to given width and height.

This should only be used when the pseudo terminal is configured for use with a terminal emulation, i.e. when isConsole() returns false.

Note: This method may not be supported on all platforms. Known platforms which support this method are: linux-x86, linux-x86_64, solaris-sparc, macosx.

Since:

5.2

exec_pty

public int exec_pty(Spawner spawner,
 String[] cmdarray,
 String[] envp,
 String dir,
 Spawner.IChannel[] chan)
             throws IOException

Throws:

IOException

Since:

5.6

waitFor

public int waitFor(Spawner spawner,
 int pid)

Since:

5.6

Restriction:

This method is not intended to be referenced by clients.
