Constructor Detail

Native

protected Native(long I64_NativeRef)

Constructor.

Parameters:

I64_NativeRef - Native instance reference.

Method Detail

openDevice

public boolean openDevice()

Description copied from interface: OutputDevice.Interface

Device opening handler. Should rather be protected, but this is not possible in a Java interface.

Specified by:

openDevice in interface OutputDevice.Interface

Returns:

true for success, false otherwise.

closeDevice

public boolean closeDevice()

Description copied from interface: OutputDevice.Interface

Device closure handler. Should rather be protected, but this is not possible in a Java interface.

Specified by:

closeDevice in interface OutputDevice.Interface

Returns:

true for success, false otherwise.

put

public final OutputDevice.Interface put(java.lang.String J_Text)

Description copied from interface: OutputDevice.Interface

Pushes characters to the output device.

Specified by:

put in interface OutputDevice.Interface

Parameters:

J_Text - String to be displayed by the device.

Returns:

The output device itself.

beep

public final void beep()

Description copied from interface: OutputDevice.Interface

Makes the output device beep.

Specified by:

beep in interface OutputDevice.Interface

cleanScreen

public final void cleanScreen()

Description copied from interface: OutputDevice.Interface

Cleans the screen.

Specified by:

cleanScreen in interface OutputDevice.Interface

getScreenInfo

public final OutputDevice.ScreenInfo getScreenInfo()

Description copied from interface: OutputDevice.Interface

Screen info accessor.

Specified by:

getScreenInfo in interface OutputDevice.Interface

Returns:

Screen info with possible ScreenInfo::UNKNOWN values.

wouldOutput

public boolean wouldOutput(OutputDevice.Interface CLI_Device)

Description copied from interface: OutputDevice.Interface

Stack overflow protection.

Specified by:

wouldOutput in interface OutputDevice.Interface

Parameters:

CLI_Device - Other device that the callee device should check it would output characters to.

Returns:

true if the callee device would redirect characters to the given device for output. Determines whether the current device would output the given device in anyway. Default implementation checks whether this is the self device.
