Method Detail

initialise

public void initialise()

Description copied from class: Console

sets up all the needed objects.

Overrides:

initialise in class FieldConsole

printIntroText

public void printIntroText()

Description copied from class: Console

Prints introductory text.

Overrides:

printIntroText in class Console

printHelp

public void printHelp()

Description copied from class: Console

Print help message.

Overrides:

printHelp in class FieldConsole

getPrompt

public java.lang.String getPrompt()

Description copied from class: Console

Prints the prompt string.

Overrides:

getPrompt in class Console

testSpecialCommands

public Console.SPEC_ACTION testSpecialCommands(java.lang.String command)

Description copied from class: Console

Checks for special commands. For example a subclass may have a verbose mode switched on of off using the command

 verbose on
 

This method can be used detected this input, perform required actions and skip normal processing by returning true. In general sub classes should call the superclass methods to test for special commands that class implements

Overrides:

testSpecialCommands in class FieldConsole

Returns:

SPEC_ACTION.CONTINUE - continue processing this equation, SPEC_ACTION.BREAK - stop processing this equation and get the next line of input, SPEC_ACTION.ALTERED - the input text has been altered, SPEC_ACTION.EXIT stop the program

See Also:

Console.split(String)

processEquation

public java.lang.Object processEquation(Node node)
                                 throws JepException

Description copied from class: Console

Performs the required operation on a node. Typically evaluates the node and prints the value.

Overrides:

processEquation in class Console

Parameters:

node - Node representing expression

Returns:

The result of the calculation

Throws:

JepException - if a Parse or evaluation error

toString

public java.lang.String toString(java.lang.Object o)

Description copied from class: Console

Return string representation of object. Used the doubleFormat if specified.

Overrides:

toString in class FieldConsole

Returns:

main

public static void main(java.lang.String[] args)

Creates a new Console object and calls run()
