enableVtp

private static boolean enableVtp(com.sun.jna.Pointer console,
 int outMode)

isWindowsSystemStream

public static boolean isWindowsSystemStream(TerminalProvider.Stream stream)

getConsoleMode

protected int getConsoleMode(com.sun.jna.Pointer console)

Specified by:

getConsoleMode in class AbstractWindowsTerminal<com.sun.jna.Pointer>

setConsoleMode

protected void setConsoleMode(com.sun.jna.Pointer console,
 int mode)

Specified by:

setConsoleMode in class AbstractWindowsTerminal<com.sun.jna.Pointer>

getSize

public Size getSize()

Description copied from interface: Terminal

Retrieve the size of the visible window

Returns:

the visible terminal size

See Also:

• Terminal.getBufferSize()

getBufferSize

public Size getBufferSize()

Description copied from interface: Terminal

Retrieve the size of the window buffer. Some terminals can be configured to have a buffer size larger than the visible window size and provide scroll bars. In such cases, this method should attempt to return the size of the whole buffer. The getBufferSize() method can be used to avoid wrapping when using the terminal in a line editing mode, while the Terminal.getSize() method should be used when using full screen mode.

Returns:

the terminal buffer size

See Also:

• Terminal.getSize()

processConsoleInput

protected boolean processConsoleInput()
                               throws IOException

Description copied from class: AbstractWindowsTerminal

Read a single input event from the input buffer and process it.

Specified by:

processConsoleInput in class AbstractWindowsTerminal<com.sun.jna.Pointer>

Returns:

true if new input was generated from the event

Throws:

IOException - if anything wrong happens

processKeyEvent

private void processKeyEvent(Kernel32.KEY_EVENT_RECORD keyEvent)
                      throws IOException

Throws:

IOException

processFocusEvent

private void processFocusEvent(boolean hasFocus)
                        throws IOException

Throws:

IOException

processMouseEvent

private void processMouseEvent(Kernel32.MOUSE_EVENT_RECORD mouseEvent)
                        throws IOException

Throws:

IOException

readConsoleInput

private Kernel32.INPUT_RECORD readConsoleInput(int dwMilliseconds)
                                        throws IOException

Throws:

IOException

getCursorPosition

public Cursor getCursorPosition(IntConsumer discarded)

Description copied from interface: Terminal

Query the terminal to report the cursor position. As the response is read from the input stream, some characters may be read before the cursor position is actually read. Those characters can be given back using org.jline.keymap.BindingReader#runMacro(String)

Specified by:

getCursorPosition in interface Terminal

Overrides:

getCursorPosition in class AbstractTerminal

Parameters:

discarded - a consumer receiving discarded characters

Returns:

null if cursor position reporting is not supported or a valid cursor position
