Constructor Details

AbstractTerminal

public AbstractTerminal(String name,
 String type)
                 throws IOException

Creates a new terminal with the specified name and type using default signal handling.

Parameters:

name - the terminal name

type - the terminal type

Throws:

IOException - if an I/O error occurs during initialization

AbstractTerminal

public AbstractTerminal(String name,
 String type,
 Terminal.SignalHandler signalHandler)
                 throws IOException

Creates a new terminal with the specified name, type, and signal handler.

Parameters:

name - the terminal name

type - the terminal type

signalHandler - the default handler for all signals

Throws:

IOException - if an I/O error occurs during initialization

Method Details

handle

public Terminal.SignalHandler handle(Signal signal,
 Terminal.SignalHandler handler)

Specified by:

handle in interface Terminal

raise

public void raise(Signal signal)

Specified by:

raise in interface Terminal

handleDefaultSignal

protected void handleDefaultSignal(Signal signal)

Handles the default behavior for a signal when no custom handler is registered. Subclasses can override this method to provide default signal handling behavior.

Parameters:

signal - the signal to handle

echoSignal

protected void echoSignal(Signal signal)

Echoes the control character representation of a signal to the terminal output. For example, SIGINT is echoed as "^C".

Parameters:

signal - the signal whose control character should be echoed

echo

public boolean echo()

Specified by:

echo in interface Terminal

echo

public boolean echo(boolean echo)

Specified by:

echo in interface Terminal

getName

public String getName()

Specified by:

getName in interface Terminal

getType

public String getType()

Returns the terminal type identifier.

Returns:

the terminal type (e.g., "xterm", "vt100")

device

public Device device()

Specified by:

device in interface Terminal
