EchoConsole

public EchoConsole()
Creates a new echo console.

Method Detail

processInput

protected java.lang.String processInput(java.lang.String line)
Description copied from class: ConsolePane
Processes the given line of input and produces whatever corresponding output is required. Output can be sent to the output stream returned by getOutputStream(), in which case it will be sent directly to the console output. Furthermore, any string returned by this routine will also be sent to the console output. This returned string may be null, in which case no extra string will be output.

Processing will be done in a separate thread, so if processing is slow then any intermediate output will be displayed to the console as it is produced.

If processing is time consuming, this routine should regularly check isProcessingCancelled() to see if the user has cancelled the processing. If so, this routine should exit as soon as possible, possibly with an appropriate error message. If isProcessingCancelled() cannot be regularly checked (such as when processing is done in exteral libraries or native routines), see internalCancelProcessing() for details on what else can be done to ensure prompt cancellation.

This routine is advised to ensure that a final newline is output.

Precondition: The console is not currently in input mode.

Specified by:
processInput in class ConsolePane
Parameters:
line - the single line of input to process.
Returns:
any additional text to output that has not already been written to the console during this routine.
