Constructor Detail

RMIInteractionsModel

public RMIInteractionsModel(MainJVM jvm,
                            ConsoleDocumentInterface cDoc,
                            File wd,
                            int historySize,
                            int writeDelay)

Constructs an InteractionsModel which can communicate with another JVM.

Parameters:

jvm - RMI interface to the slave JVM

cDoc - document to use in the InteractionsDocument

historySize - Number of lines to store in the history

writeDelay - Number of milliseconds to wait after each println

Method Detail

Specified by:

_interpret in class InteractionsModel

Parameters:

toEval - command to be evaluated

getVariableToString

public String getVariableToString(String var)

Gets the string representation of the value of a variable in the current interpreter.

Specified by:

getVariableToString in class InteractionsModel

Parameters:

var - the name of the variable

Returns:

A string representation of the value, or null if the variable is not defined.

getVariableType

public String getVariableType(String var)

Gets the class name of a variable in the current interpreter.

Specified by:

getVariableType in class InteractionsModel

Parameters:

var - the name of the variable

addProjectClassPath

public void addProjectClassPath(File f)
