Field Detail

ets

private EmulatedTerminalState ets

Emulated terminal simulator implemented in a driver-specific manner.

Constructor Detail

ChuiPrimitives

public ChuiPrimitives(EmulatedTerminalState ets)

Constructor.

Parameters:

ets - Emulated terminal simulator instance used for direct drawing.

Method Detail

getEmulatedTerminalState

public EmulatedTerminalState getEmulatedTerminalState()

Obtain the core worker that implements the emulated terminal.

Returns:

The worker instance.

append

public void append(java.lang.String str,
                   Color color)

Add a string to the virtual terminal at the current cursor position. This move the cursor after each character is output, naturally wrapping the cursor to the beginning of the next row or to the beginning of the screen as necessary.

Specified by:

append in class BasePrimitives

Parameters:

str - The text to output.

color - The color (includes attributes) in which to output the text. All text will be output with the same color.

cursorAt

public boolean cursorAt(int x,
                        int y)

Position the virtual cursor during the drawing.

Specified by:

cursorAt in class BasePrimitives

Parameters:

x - New cursor X.

y - New cursor Y.

Returns:

true if cursor positioning succeeded.

cursorStay

public boolean cursorStay(int x,
                          int y)

Position the real cursor.

Specified by:

cursorStay in class BasePrimitives

Parameters:

x - New cursor X.

y - New cursor Y.

Returns:

true if cursor positioning succeeded.

getX

public int getX()

Get absolute X position of the cursor.

Specified by:

getX in class BasePrimitives

Returns:

The X position of the cursor.

getY

public int getY()

Get absolute Y position of the cursor.

Specified by:

getY in class BasePrimitives

Returns:

The Y position of the cursor.

screenHeight

public int screenHeight()

Gets the number of rows on the screen.

Returns:

The number of rows (lines of characters).

screenWidth

public int screenWidth()

Gets the number of columns on the screen.

Returns:

The number of columns (in characters).

sync

public void sync()

Synchronize the state of the physical terminal with the state of the virtual terminal.

updateScreen

public void updateScreen(ScreenData screen)

Perform a bulk output operation for the whole screen at once with output masking when desired. Set the cursor afterwards to the given X and Y coordinates in the screen instance.

The screen container is safe for use with any UNICODE character.

Overrides:

updateScreen in class BasePrimitives

Parameters:

screen - Container for whole screen content and cursor position.
