Class UnixTerminal

java.lang.Object
  jline.Terminal
      jline.UnixTerminal

public class UnixTerminal

extends Terminal

Terminal that is used for unix platforms. Terminal initialization is handled by issuing the stty command against the /dev/tty file to disable character echoing and enable character input. All known unix systems (including Linux and Macintosh OS X) support the stty), so this implementation should work for an reasonable POSIX system.

isSupported

public boolean isSupported()

getEcho

public boolean getEcho()

Description copied from class: Terminal

Returns true if the terminal will echo all characters type.

getEcho in class Terminal

getTerminalWidth

public int getTerminalWidth()

Returns the value of "stty size" width param. Note: this method caches the value from the first time it is called in order to increase speed, which means that changing to size of the terminal will not be reflected in the console.

Specified by:

getTerminalWidth in class Terminal

getTerminalHeight

public int getTerminalHeight()

Returns the value of "stty size" height param. Note: this method caches the value from the first time it is called in order to increase speed, which means that changing to size of the terminal will not be reflected in the console.
