Method Detail

getLoggingFacade

public MyLoggingFacade getLoggingFacade()

setLoggingFacade

public void setLoggingFacade(MyLoggingFacade loggingFacade)

getCommandCompletion

public ArrayList<String> getCommandCompletion()

setCommandCompletion

public void setCommandCompletion(ArrayList<String> commandCompletion)

clearCommandBuffer

public void clearCommandBuffer()

addCommandHistory

public void addCommandHistory(List<String> commands)

readline

public String readline()
                throws IOException

Description copied from interface: IOInterface

Read a line of input with no prompt.

Specified by:

readline in interface IOInterface

Returns:

Throws:

IOException

readline

public String readline(String prompt)
                throws IOException

Description copied from interface: IOInterface

read a line of input, printing the prompt (on the left) first. The prompt is not returned.

Specified by:

readline in interface IOInterface

Returns:

Throws:

IOException

getTerminal

public ISO6429Terminal getTerminal()
                            throws IOException

Throws:

IOException

print

public void print(Object x)

Description copied from interface: IOInterface

Print the string representation of an object, without a carriage return.

Specified by:

print in interface IOInterface

println

public void println(Object x)

Description copied from interface: IOInterface

Print the string representation of an object with a carriage return.

Specified by:

println in interface IOInterface

flush

public void flush()

Description copied from interface: IOInterface

Flush anything waiting to be printed. Normally this is done with the print methods.

Specified by:

flush in interface IOInterface

init

protected void init(boolean noBanner)
             throws IOException

Throws:

IOException

getScreenSize

public int[] getScreenSize()
                    throws IOException

Throws:

IOException

main

public static void main(String[] args)

info

protected void info(String x)

warn

protected void warn(String x,
                    Throwable t)

debug

protected void debug(String x)

clearQueue

public void clearQueue()

Description copied from interface: IOInterface

Some implementations will have a queue e.g. if the user paste text from the clipboard). The IOInterface.readline(String) methods will queue these up and return them in sequence -- this is done silently. If for some reason you need only a single line and want to discard anything else, invoke this.

Specified by:

clearQueue in interface IOInterface

isQueueEmpty

public boolean isQueueEmpty()

Description copied from interface: IOInterface

Check if the queue is empty.

Specified by:

isQueueEmpty in interface IOInterface

Returns:

setBufferingOn

public void setBufferingOn(boolean bufferingOn)

Description copied from interface: IOInterface

If this object supports buffering of commands, this will toggle it. Buffering means that every result of IOInterface.readline(String) will be stored and up down arrows will cycle through them.

Specified by:

setBufferingOn in interface IOInterface

isBufferingOn

public boolean isBufferingOn()

Description copied from interface: IOInterface

return current state of buffering.

Specified by:

isBufferingOn in interface IOInterface

Returns:
