MainJVM.DummyInteractionsModel

public MainJVM.DummyInteractionsModel()

Method Detail

getDebugPort

public int getDebugPort()
                 throws IOException

Description copied from interface: InteractionsModelCallback

Returns an available port number to use for debugging a remote interpreter.

Specified by:

getDebugPort in interface InteractionsModelCallback

Throws:

IOException - if unable to get a valid port number.

replSystemOutPrint

public void replSystemOutPrint(String s)

Description copied from interface: InteractionsModelCallback

Called when the repl prints to System.out.

Specified by:

replSystemOutPrint in interface InteractionsModelCallback

Parameters:

s - String to print

replSystemErrPrint

public void replSystemErrPrint(String s)

Description copied from interface: InteractionsModelCallback

Called when the repl prints to System.err.

Specified by:

replSystemErrPrint in interface InteractionsModelCallback

Parameters:

s - String to print

getConsoleInput

public String getConsoleInput()

Description copied from interface: InteractionsModelCallback

Called when input is request from System.in.

Specified by:

getConsoleInput in interface InteractionsModelCallback

Returns:

the input given to System.in

setInputListener

public void setInputListener(InputListener il)

Description copied from interface: InteractionsModelCallback

Sets the listener for any type of single-source input event. The listener can only be changed with the changeInputListener method.

Specified by:

setInputListener in interface InteractionsModelCallback

Parameters:

il - a listener that reacts to input requests

changeInputListener

public void changeInputListener(InputListener from,
                                InputListener to)

Description copied from interface: InteractionsModelCallback

Changes the input listener. Takes in the old listener to ensure that the owner of the original listener is aware that it is being changed.

Specified by:

changeInputListener in interface InteractionsModelCallback

Parameters:

from - the previous listener

to - the listener to install

replReturnedVoid

public void replReturnedVoid()

Description copied from interface: InteractionsModelCallback

Signifies that the most recent interpretation completed successfully, returning no value.

Specified by:

replReturnedVoid in interface InteractionsModelCallback

replReturnedResult

public void replReturnedResult(String result,
                               String style)

Description copied from interface: InteractionsModelCallback

Signifies that the most recent interpretation completed successfully, returning a value.

Specified by:

replReturnedResult in interface InteractionsModelCallback

Parameters:

result - The .toString-ed version of the value that was returned by the interpretation. We must return the String form because returning the Object directly would require the data type to be serializable.

replThrewException

public void replThrewException(String message,
                               StackTraceElement[] stackTrace)

Description copied from interface: InteractionsModelCallback

Signifies that the most recent interpretation was ended due to an exception being thrown.

Specified by:

replThrewException in interface InteractionsModelCallback

Parameters:

message - The exception's message

replThrewException

public void replThrewException(String message)

Description copied from interface: InteractionsModelCallback

Signifies that the most recent interpretation was ended due to an exception being thrown.

Specified by:

replThrewException in interface InteractionsModelCallback

Parameters:

message - The exception's message

replReturnedSyntaxError

public void replReturnedSyntaxError(String errorMessage,
                                    String interaction,
                                    int startRow,
                                    int startCol,
                                    int endRow,
                                    int endCol)

Description copied from interface: InteractionsModelCallback

Signifies that the most recent interpretation was preempted by a syntax error.

Specified by:
